More than half of school-aged kids don't get enough sleep, says new study

New research shows that more than half of school-age children aren't getting the recommended nine hours of sleep a night, and they're losing out on more than just rest. Sleep-deprived kids don't show as many signs of development, according to an abstract being presented before experts this month.

"Our research shows that children who get enough sleep are more likely to demonstrate measures of childhood flourishing in comparison to children with insufficient sleep," Dr. Hoi See Tsao, author of the abstract, said in a press release about the findings, which she will present at the American Academy of Pediatrics 2019 National Conference and Exhibition in New Orleans.

Researchers used data from the 2016-2017 National Survey of Childrens' Health, in which caregivers and parents gave self-reported answers. Of the 49,050 children ages 6-17 years old represented in the survey, only 47.6% got an average of nine hours of sleep on weeknights.

AAP recommends the guidelines set by the American Academy of Sleep Medicine, which state that children ages 6-12 years should sleep 9-12 hours a night, while teenagers ages 13-18 should sleep 8-10 hours. Infants need 12-16 hours, toddlers need 11-14 and preschoolers need 10-13 hours of sleep.

We already knew that sleep makes kids (and adults) healthier, affecting everything from weight and growth to attention and temperament. What this new research shows is the combined advantage for what pediatricians call "flourishing markers."

The survey asked whether children showed interest and curiosity in new things, cared about school, did their homework, completed tasks, and stayed calm in the face of a challenge. Those who got at least nine hours had better odds in all but that last category (only half of all kids, it seems, can be calm and collected in tough situations). The kids who didn't get enough sleep were about 12% less likely to flourish in all four categories.

The biggest difference was in homework. Caregivers said 68.4% of kids who got eight or fewer hours of sleep definitely did all required homework, while 80.2% who got nine or more hours definitely did all of it.

Tsao, a pediatrician at Massachusetts General Hospital would like healthcare providers to do more to educate parents. "This research reinforces the importance of increasing efforts to maximize sleep sufficiency for children including addressing digital media usage, bedtime routines and school duration and start times," Tsao told Newsweek.

This also a good reminder for parents and educators that if a child doesn't appear engaged at school, they might just need to get more sleep. If any other school systems are looking into following California's example and delaying start times for middle and high school, this is one more reason to go for it.

Time-saving formula tips our editors swear by

Less time making bottles, more time snuggling.

As a new parent, it can feel like feeding your baby is a full-time job—with a very demanding nightshift. Add in the additional steps it takes to prepare a bottle of formula and, well… we don't blame you if you're eager to save some time when you can. After all, that means more time for snuggling your baby or practicing your own well-deserved self-care.

Here's the upside: Many, many formula-feeding mamas before you have experienced the same thing, and they've developed some excellent tricks that can help you mix up a bottle in record time. Here are the best time-saving formula tips from editors here at Motherly.

1. Use room temperature water

The top suggestion that came up time and time again was to introduce bottles with room temperature water from the beginning. That way, you can make a bottle whenever you need it without worrying about warming up water—which is a total lifesaver when you have to make a bottle on the go or in the middle of the night.

2. Buy online to save shopping time

You'll need a lot of formula throughout the first year and beyond—so finding a brand like Comforts, which offers high-quality infant formula at lower prices, will help you save a substantial amount of money. Not to mention, you can order online or find the formula on shelves during your standard shopping trip—and that'll save you so much time and effort as well.

3. Pre-measure nighttime bottles

The middle of the night is the last time you'll want to spend precious minutes mixing up a bottle. Instead, our editors suggest measuring out the correct amount of powder formula into a bottle and putting the necessary portion of water on your bedside table. That way, all you have to do is roll over and combine the water and formula in the bottle before feeding your baby. Sounds so much better than hiking all the way to the kitchen and back at 3 am, right?

4. Divide serving sizes for outings

Before leaving the house with your baby, divvy up any portions of formula and water that you may need during your outing. Then, when your baby is hungry, just combine the pre-measured water and powder serving in the bottle. Our editors confirm this is much easier than trying to portion out the right amount of water or formula while riding in the car.

5. Memorize the mental math

Soon enough, you'll be able to prepare a bottle in your sleep. But, especially in the beginning or when increasing your baby's serving, the mental math can take a bit of time. If #mombrain makes it tough to commit the measurements to memory, write up a cheat sheet for yourself or anyone else who will prepare your baby's bottle.

6. Warm up chilled formula with water

If you're the savvy kind of mom who prepares and refrigerates bottles for the day in advance, you'll probably want to bring it up to room temperature before serving. Rather than purchase a bottle warmer, our editors say the old-fashioned method works incredibly well: Just plunge the sealed bottle in a bowl of warm water for a few minutes and—voila!—it's ready to serve.

It's science: Why your baby stops crying when you stand up

A fascinating study explains why.

When your baby is crying, it feels nearly instinctual to stand up to rock, sway and soothe them. That's because standing up to calm babies is instinctual—driven by centuries of positive feedback from calmed babies, researchers have found.

"Infants under 6 months of age carried by a walking mother immediately stopped voluntary movement and crying and exhibited a rapid heart rate decrease, compared with holding by a sitting mother," say authors of a 2013 study published in Current Biology.

Even more striking: This coordinated set of actions—the mother standing and the baby calming—is observed in other mammal species, too. Using pharmacologic and genetic interventions with mice, the authors say, "We identified strikingly similar responses in mouse pups as defined by immobility and diminished ultrasonic vocalizations and heart rate."
