“I wonder how we can get them to sleep more.”


This simple thought, expressed by my wife, not even a question, became a challenge to me. My engineer mind took this as a problem to be solved, and when a software developer sees a problem, they devise tests. Luckily, I knew the perfect system for testing out some ideas in a controlled and measurable setting. And with twins, testing would be even easier. Welcome to parenting, A/B testing style.

A/B testing is used all over the web. You likely encounter it dozens, if not hundreds of times a day, without even noticing it. All the big tech companies do it, using it as a tool to test the performance of ideas and measure them.

Google is famous for testing 41 shades of blue for search results. Designers allegedly couldn’t decide which of two shades to use, so they tested 41 in total to see which led to the more users clicking on the results.

Facebook tests different experiences within the feed constantly. Amazon even changes around the buy buttons and cart layouts fairly often. You may notice these if you ever log in from a new computer or see a friend using a site that looks subtly different from yours.

A/B testing is used to test one or more “treatments” or experiments over a “control” or the existing experience. A metric is measured, usually based on a user action such as a click through or “conversion” with a baseline against the control.

For the Google example, they might test the likelihood of users clicking through to at least one result with the different shade. After a statistically significant period of time, often a week or two, whichever experience has a better rate will be chosen as the winner and becomes the new control.

Where this gets really complicated is when multiple experiments are run at the same time or when the percentage of users is not equally split. Here a complicated knowledge of statistics is needed. Or the use of any of the many powerful testing tools available. At Audible and Amazon, we test experiences like this all the time. It’s the best way to see how users actually behave as often what users say they will do and what they do can be slightly different.

Charting results

I decided to use this method of testing with the boys to see if we could increase the most important metric in the house, as anyone with 10-week old children, especially twins, knows: sleep times. Using one of the boys as a control and the other as the treatment – nevermind the fact that no one would describe any part of our lives right now with the words “control” or “treatment” – I tested several theories about length of sleep, baselined against the control.

In any experiment, accurate measurement and data tracking are critical. Often a success metric is chosen due to the availability of data or measurability. You don’t want to be trying to measure something that takes longer to measure than it does to change the test or test input. Luckily measuring sleep is about as easy as it gets.

When they wake up at night, we just write it down. This is exactly what we’ve been doing since the day they were born as the nurses at the hospital instructed us. We’ve gone through several notebooks already, but it’s so easy to track. For this, we even started importing the data into a spreadsheet to see the impact more visually.

 

Big Data

First, we tested increasing the amount given at the feeding immediately before bedtime. Instead of the normal four ounces, we tried five, then six. To prevent bias from one child, we alternated who was the test and who was the control since they seem to be on alternating cycles. While one child had a larger evening feeding, the other would stay at four ounces. The result: inconclusive.
Both children seemed to start increasing length of sleep anyway during this period. They both slept almost the exact same length of time as well. There was one night where an increased feeding correlated with a record 5.5 hour stretch of sleep, but one data point is insignificant in this dataset.
It was also hard to continue testing this as anything beyond five ounces had a high likelihood of being spit out a few minutes after eating.

Next was a secret whispered about in the dark corners of parent blogs around the web and passed from parent to fellow parent, at least in my office, gripe water. Ok maybe it isn’t that much of a secret, but it took us a while to try it. Supposedly this mix of herbs and spices, as opposed to KFC’s blend, would settle stomachs from reflux and gas, especially overnight, resulting in longer sleep.

After a week of testing, we found it did actually help with reflux, especially spit ups, and though we didn’t track individual burps or farts, seemed to reduce them as well. The length of sleep was not impacted much, though. We did see a small increase on average, between 20 and 30 minutes, but again this may have been natural increases due to age.

No reflux equals a happy baby

After gripe water, which became the new control, we tested an extra feeding before bed. The boys were starting to do this naturally on their own, anyway, and we had been trying to prevent it. However, it seemed like an opportunity ripe for testing, so we gave it a shot. Many children will “cluster” feed before bed, with a second feeding only a short time after the previous one. We did this feeding about 1.5 to 2 hours after the previous, compared to 3 hours normally. In this feeding, we tried 4 ounces compared with the 4–5 they normally take during daytime feedings. Sometimes they would refuse to take more than 3. Of all the experiments, this seemed to work best. We saw increases in up to an extra hour of sleep as a result, though often not until a few days into the experiment, apparently this takes time to affect sleep patterns. A good lesson for A/B tests is that sometimes there is a several day adjustment period while people figure out the new treatment and adjust. It’s important to capture both the adjustment period results and the post-adjustment ones, though. Apple has famously neglected the adjustment period on several product launches, notably maps.

Last, we tested keeping them awake longer during the day. Our hypothesis was that they would therefore, be more tired at night and would sleep longer as a result. This may have been slightly true, we saw minor increases in length of sleep, but we didn’t account for the stress and exhaustion it would cause by keeping them awake and making them unhappy. It also took significantly longer to get them to settle down and sleep at night as they were overtired and fussy. The lesson for testing: don’t sacrifice other metrics for a small gain in one.

You can’t make me sleep!

Many of these tests were inconclusive. This is largely due to the sample size. With a sample population like Facebook, tests can be done in small segments and achieve statistical significance very quickly. With twins, it’s hard to know what is a real result and what is personality or natural progression. In order to more accurately test, we may need to increase the sample size. Triplets would come in handy for this. Maybe someone else’s triplets though, we are definitely not ready for that!

This also shows the importance of the test, measure, iterate process. Though several of the methods didn’t show large improvements, put together they may. By using the treatment as the control when it outperforms the control, small improvements get stacked. By continuing to try new things quickly and moving on, it’s easy to come up with new ideas to try. You don’t need to move the mountain, just move little handfuls of dirt over a long time. With this approach to parenting, the boys can continuously grow as well. And with luck, so will our sanity, well-being, and lives as parents.

The holidays are quickly on their way, and while there are tons of ways to celebrate, you should feel free to get a little creative with it and make your own traditions (there's no law requiring you to dress everyone in matching red velvet jumpers to sit on Santa's lap). So instead of battling between getting the perfect picture and your baby's natural urge to wiggle, harness the power of those inevitable Hallmark moments—the first giggle, the budding personality, the two-toothed grin—to make your December super special.

Here are six new traditions you can start to meet your little one where they are and celebrate joy in this season—without all the stress.

1. Make DIY ornaments

Decorating the tree is a beloved tradition, and having a little one is all the more reason to get into the spirit of it. Get the baby—and the rest of the family—involved in the fun by letting everyone color or paint on an unbreakable, homemade ornament and hang them towards the bottom of the tree. And sure, your infant may not create any masterpieces at this age, but not only will the precious family heirlooms stay higher up (read: away from tiny hands), you'll also be creating keepsakes to build on for years to come.

2. Bring a holiday scene to life

Connecting your children to the spirit of the season is an important part of teaching them what it's all about, but it's not always so easy to do through books and stories alone. Instead, offer them the chance to live it out! Whether you celebrate Hanukkah, Christmas or another significant holiday, playing pretend is the ideal way to teach and have fun along the way for everyone in the family. Use a kid-friendly nativity book as a guide or make your own menorah as you explore the story of the oil that burned for 8 nights—whatever your religion, there's an important tale to tell.

3. Make video cards

There is joy in receiving physical mail and holiday cards are a wonderful way to make your loved ones feel special. But don't stop there! Record a video greeting to send to your nearest and dearest to keep even the most far-away relatives feel like they're right there with you. Everyone will love seeing the baby's latest milestones in live-action, and it's a great way to spread the season's warmest greetings.

4. Start a time capsule box

Making (and maintaining) a baby book is a fabulous idea, but sometimes keeping it up-to-date gets lost in the shuffle of parenthood. Use the holiday season as a time to reconnect with all those beloved memories for your kiddo by starting an annual time capsule box: Each year, have all members of the family add one item of their choosing (or your choosing, depending on age) to the box and label it with a little note. Things can range from a favorite holiday-themed blanket or toy to something they no longer need but aren't ready to throw away.

5. Begin a culinary tradition

Nothing says "cozy" like a yummy-smelling kitchen filled with laughter. While your tot may still be too small to really help in the kitchen, it's never too early to kickstart their love of cooking. Pick a recipe you'll make every year and get them "involved" with a spoon and an empty mixing bowl. You'll get to enjoy the fruits of your labor together and it'll help encourage them to cook with you more year-round, too.

6. Play king for a day

We all know that as babies grow up—independence is a priority, no matter how ready for it we really are. This year, give them the gift of being in charge. By allowing your little one to eat what they want, wear what they pick (a sparkly tutu? No problem. An adorable Christmas cape? Great!) and play with what they prefer, you'll be empowering them with a sense of self and giving yourself the gift of hilarious photo ops for years to come.

As an ESPN anchor Kevin Negandhi talks to a lot of pro athletes. But as a parent he knows that sometimes raising kids is as hard as training for the big leagues (seriously, science proves that kids energy levels surpass endurance athletes' and parents are running after those kids).

Negandhi knows what it's like to be face-to-face with athletes that so many people idolize, but he also knows that a parent can be more influential than any big league idol, and that's why he's working with Dove Men+Care SPORTCARE to put real dads in the spotlight.

"We have a platform to showcase what they do as everyday athletes, but also as everyday men, everyday fathers," says Negandhi, who has three kids himself. He tells Motherly he tries to make sure he's active with his kids—playing sports with them so that they understand the importance of staying active—but also staying active with the kids when the touch football ends and the real parenting endurance test begins. Like many modern fathers, Negandhi is committed to doing more childcare than his own father did.

"My mom did everything in our house," he tells Motherly. "My dad worked, but my mom worked as well. And she did everything. She raised us. But at the same time she showed me another side. And many times growing up I said, 'How can I be different than my father?'"

Being involved with his kids and doing more of the unpaid work in his household than his own dad did is how Negandhi is doing it, and he's taking time to showcase three fellow dads who—while sharing their names with professional athletes—certainly don't get as much credit as the pros.

That is actually something of a problem in media right now. According to a recent survey by Dove Men+Care, 70% of men wish regular guys who are athletes (but not professionals) got more attention in sports media. Because as much as winning the Superbowl or making it to the major leagues should be celebrated, being a dad who is physically active and active in raising his kids should be celebrated, too.

Research shows that when kids grow up seeing dads exercise they are healthier, and while these three men happen to share their names with famous athletes, they don't get the same glory. So Negandhi and Dove Men+Care are giving these hard working dads some recognition.

Alvin Suarez

Alvin Suarez is teaching his kids that having a disability doesn't disqualify you from being an athlete. As a visually-impaired person, Alvin isn't the standard athlete we see represented in media. He plays Goalball, a sport that relies on keen ear-hand coordination, and he is certainly a keen father, chasing after his twin girls.

Alvin says the difference between sports and fatherhood is that you can train for sports, while parenthood takes you by surprise. "I try to be a good role model for my daughters and I want everyone to know that everyone has potential and that there is no such thing as a nobody."

Alvin has won championships as a Goalball player, but says holding his daughters in his arms for the first time was like winning a medal but multiplied by a million.

Sean Williams

Sean Williams is committed to his community and his kids. He uses physical fitness to connect with his kids and to, literally, save lives. A volunteer firefighter, Sean keeps fit so that he can use his body and energy to maximum impact. He isn't just changing the lives of people impacted by fires, but also his fellow dads.

The founder of The Dad Gang, an organization committed to celebrating and telling the real story of black fatherhood, Sean has created a space for dads to connect with their children and each other while staying active.

"One of the challenges we put out on social media is where you do pushups with our kids on our backs and that merges fatherhood and fitness," he explains.

If there was a Super Bowl for community service, Sean would be wearing the ring.

Chris Paul

A Marine Corps veteran, Chris needs a ton of energy to keep up with his blended family. It started out as an "all-girl Brady Bunch" he explains, as his wife and he had six daughters between them, but they've since added a boy to the family which now included seven kids. .

He's basically got his own sports team at home so it makes sense that Chris is super committed to staying fit for them. The Marine turned realtor takes time to help other dads in his community stay fit and knows when to draw boundaries to protect his time with his kids.

He's got some good endurance, but he's not going to work 15 hours a day when his kids are waiting at home for him. Chris says in former times dads were often passive figures in their kids' lives as the child rearing was done by others.

Like the other men, he's changing that. "I'm an active participant and I want to make sure that I can contribute to my children's lives."

Back in 2017 when we learned Beyoncé was starring in a new remake of The Lion King I was thrilled. My son (my only child) was almost 2 years old and I told my partner I wanted The Lion King to be our son's first movie theatre experience. Going to see the original Lion King in a movie theatre was a big deal to me as a kid and I wanted to recreate that experience for my son.

Flash forward to July 2019 and The Lion King is in theaters—but my son and I are not. Turns out I really overestimated how long 3-year-olds can sit still. While my son loves watching 1994's Lion King at home (he always stands on the couch and lifts his stuffed animals to the sky during "Circle of Life") he's just not quite subdued enough for the cinema yet.

FEATURED VIDEO

So we have been waiting to see The Lion King at home, and now we finally can! October 11 marks the film's digital home video release, and the Blu-ray hits stores on October 22.

Rob Legato, a VFX supervisor on the film, tells Motherly that "the visuals are so well preserved on 4K and newer television sets that it is literally the mini theatre experience and you're not missing much by seeing it at home."

Basically, the digital version is going to be just as awesome as seeing it in theaters, except that we will be able to pause for potty breaks and my kiddo can stand on his seat pretending to be Rafiki without blocking anyone's view.

The movie is, of course, incredible, but so are the animals it's based on. Screening the movie at home is an amazing way to start conversations with your kids about the various animals in the film as they are of course more similar to the real animals they are based on then their animated counterparts were in 1994.

The filmmakers went to Africa to research the animals they were bringing to life and they also spent a ton of time at the Harambe Wildlife Reserve inside Disney's Animal Kingdom in Orlando, Florida watching various species to try to make their movements as realistic as possible. There, 34 species live on 110 acres and the filmmakers got to watch them closely, making this film incredibly detailed.

Some of the animal experts who work with these animals on a daily basis say that when they watch The Lion King, they can actually tell which characters are based on which of the animals they know in real life.

"This film presented a really wonderful and unique opportunity to bring the production crew to the animals here at Disney's Animal Kingdom. They spent about 6 weeks here collecting reference footage of the animals here and we partnered really closely with the animal care teams at Disney's Animal Kingdom to make sure that all of the filming that we were doing, the impact to the animals was minimized," says Jon Ross of Disney's Animals in TV and Film department

The film crew watched the animals from a distance, which is something families can also do at Disney's Animal Kingdom by taking the Kilimanjaro Safari or staying in Jambo House at the Animal Kingdom Lodge, where giraffes and other animals can be seen right from hotel balconies.

But the work Disney is doing with the animals is more than a tourist attraction. The company is serious about conservation and protecting the animal species featured in the park and in its films. "Tied to the Lion King film we launched the Protect the Pride initiative," Claire Martin of Disney's Conservation & Partnerships team tells Motherly. "We realized that we'd lost half of the world's lions since the first Lion King film debuted and we want to turn that around, so we're working with the Wildlife Conservation Network's Lion Recovery Fund to help their vision to double the amount of lions in the wild by 2050," she explains.

Marin suggests that parents watching The Lion King with their kids can use the film to talk to their children about conservation issues and continue the education long after the end credits roll. "We encourage people to learn more, visit the website, get involved and learn more about how they can make an impact on lions and other wildlife across Africa," says Martin.

Through the website, parents can even download an activity packet (you can print it and make your kids a cool book) with all kinds of information and cool activities and to help kids feed their lion obsession in an educational way even when screen time is over.

The Lion King is available to stream now and will be on Blu-ray October 22 (with even more educational features about the animals!)

For those without a toddler glued to the screen, Blippi is the colorfully dressed, bespectacled YouTube alter ego of Stevin John. He delights children by acting like a little kid as he visits farms, indoor playgrounds, construction sites and more, teaching simple lessons and singing songs about everything he sees. His channel has 5.71 million subscribers, with hits like "The Excavator Song" racking up 50 million views.

This kind of success meant he was long overdue to take the show on the road. Earlier this week, he announced a 30-date U.S. tour with an interview on Billboard, as well as on his social media. But now parents of Blippi fans, are concerned that they won't get the "real" Blippi when they attend Blippi Live shows next year.

FEATURED VIDEO

Parents flocked to his site to purchase tickets, which cost $26-$70, for the shows running in February and March 2020. But some of them hadn't read the interview, nor did they notice the fine print on the FAQ page of the Blippi Live site that said Stevin John himself was not going to be on the stage.

"I won't be on the road, but I am obviously extremely involved with the whole process," John told Billboard. "Blippi is as a character and I'm the creative force behind it, but since YouTube is a monster and all of these platforms are really crazy I can't go on the road for many weeks or months at a time."

Some parents had even spent $40-$51 on the after-show meet-and-greet before they realized that their kids would be meeting an unfamiliar "performer" instead of John. Many reacted with outrage and immediately tried to get a refund, according to Buzzfeed News.

"I didn't find out until five seconds after I submitted my payment and Ticketmaster refused to refund me," Angelina Sakowski told Buzzfeed after she bought tickets to a New Jersey show.

Stephen Shaw, the producer and promoter of the Blippi Live show, told Buzzfeed that his company would be sending parents a letter informing them about the replacement performer and would offer refunds.

They have also since added this line to the Blippi Live site: "Stevin John is the creator of Blippi and acts as the writer and creative force behind the Blippi character. Now that Blippi has evolved as a character he is excited that a dynamic stage performer has been cast as Blippi to entertain and thrill audiences across all of the tour markets."

It's hard to guess whether Blippi's actual target audience—i.e., not the upset parents—would care that stage Blippi was a slightly different person than the one they see on screens. After all, the Baby Sharks in the live show are 3D and therefore slightly different from the animated versions we all know and love/hate.

Stevin John issued a statement on the official Blippi Instagram account this week, which reads, in part: "We tried to make it clear that I would not be the character at the live show (via Billboard Exclusive Interview + FAQ on BlippiLive.com) but I'm sorry it seems that wasn't enough. We have adjusted and continue to make it even more apparent that it's not going to be me on stage. I will be the creative force behind the live show, as a producer, a writer, and also I am personally casting the live theater performer to play the character on stage."
