Expert tips on keeping baby safe during summer sleep.

How Warmer Temps Affect Baby’s Sleep

Summer can be a tricky season to keep a baby sleeping safely and comfortably. Those little babies of ours have a hard time regulating their body temperatures as well as us adults. And they have an especially tough time during a season filled with alternating blasts of air conditioning and intense heat-rays of sun.

Why all the fuss? Sleep temperature is a safety issue: when babies are hot, they have a harder time arousing, which can increase the risk of SIDS. But temperature is also about comfort, which can mean the difference between baby getting peaceful shut-eye or pulling an all-nighter. When body temperature dips at night (as it’s naturally inclined to do), it not only triggers the brain to get ready for sleep, but also results in deeper, better sleep. So keeping baby’s head nice and cool, and keeping his or her room temperature between the ideal 65 and 70 degrees, is key to the best night of baby (and, ahem, your) sleep.

Luckily, there are plenty of temperature regulating tricks and gear that can help your baby sleep like, well, a baby. Bedgear’s new Baby Performance Bedding line, for example, uses heat and moisture-wicking fabric technologies to help children regulate temperature and drift off to dreamland without a sweat. Before you head off into the hot and sticky summer, bedgear Pediatric sleep consultant Ingrid Prueher shares how you can get baby to sleep safe and sound no matter what your situation.

Situation 1: The AC in our nursery goes on and off all night, which means that the temperature fluctuates. How do I make sure that baby stays comfortable throughout the night?

In situations like this, I recommend that you use the AC during the day and fans all night to keep the temperature consistent. The on and off of the AC noise, and the fluctuation of the temperature in the room, will wake the baby up all night long. I would also recommend using bedgear Ver-Tex® temperature regulating waterproof crib mattress protector that deflects heat and repels moisture so baby sleeps cool dry and at the ideal temperature.

Situation 2: Baby loves to naps in the stroller. It’s 85 degrees and sunny out. What precautions should I take to keep baby from overheating?

Though the baby has learned to take naps in the stroller, it would be worth it to teach the baby to sleep in their home sleep environment instead on a more consistent basis. Since we live on the east coast, we know that we are not fortunate to have great weather all year round. This makes it impossible for the caregivers to provide a nap for the baby every day outside. If the caretakers had to leave the home environment during sleep times, I would recommend covering the stroller in a shade to protect him or her from UV rays and dressing the baby properly with just a onesie and a diaper. Ideally, the baby will not be exposed to the sun for long periods of time, and the caregiver will do everything to try to keep the baby in shaded areas during rest times.

Situation 3: We are going on a trip and don’t know the sleeping situation yet — it may be a house with no AC or a hotel with a strong AC unit. How can I prepare for any sleeping temperature, especially when I can’t control it?

I would recommend looking into fan or AC rentals in the area, just in case. If you cannot find one, it would be worth it to see if there is a hardware store nearby that sells fans. Depending on where you are going, the temperature of the destination maybe cool at night, and you can always end up opening the window to let in fresh air if the AC gets too cold. The key is the layers of clothing. The best way to gauge if the baby is too hot or too cold is to feel the tip of the nose and hands. If the hands are too cold, add another layer of clothing. If the baby is sweating, then strip down more.

Situation 4: We are co-sleeping with baby, adding body heat to the already high temps. How do I make sure baby doesn’t get too hot in our bed?

When bed sharing, it's imperative that safety precautions be taken if the child is under one year, as recommended by the American Academy of Pediatrics. The bed mattress should be placed on the floor, and use bedgear Dri-Tec® moisture wicking performance sheets. These breathable performance sheets wick away heat and moisture and regulate the body's temperature. I would also recommend using fans in the room if AC is not available. It's ideal if the baby is wearing a onesie with a diaper, especially if the room is too hot. You can go to the extent of having the baby only in a diaper, if need be.

    Why right now is the best time for a drivable getaway

    Flexible schedules mean more vacation options. 🙌

    Looking back now, last winter feels like a lifetime ago. At the time, my husband and I were eagerly planning our summer vacation just as we've done in years past. You know how the next part goes: COVID-19 came into the picture and changed our plans not only for vacationing, but for so much else in life.

    In the time since then, we've gained a truly valuable new perspective on what matters—and realized we don't have to look so far to make beautiful memories with our kids. By exploring getaways within driving distance of our home, we've developed a new appreciation for the ability to "pack up the car and go."

    Of course, that isn't to say that travel is the carefree adventure it once was. With COVID-19 still a very big part of the equation, we've become much more diligent about planning trips that allow for social distancing and exceed cleanliness standards. That's why we've exclusively turned to Vrbo, which helps us find nearby accommodations that meet our new criteria. Better yet?

    Thanks to the money we've saved by skipping air travel and our remote-friendly work schedules, we're able to continue with the trips throughout the fall.

    Here are a few more reasons we believe it's a great time for drivable getaways.

    Flexible schedules allow us to mix work + play.

    After months of lockdown, my family was definitely itching for a change of scenery as the summer began. By looking at drivable destinations with a fresh set of eyes—and some helpful accommodation-finding filters on Vrbo—we were able to find private houses that meet our needs. (Like comfortably fitting our family of five without anyone having to sleep on a pull-out couch!)

    With space to spread out and feel like a home away from home, we quickly realized that we didn't need to limit our getaways to the weekends—instead we could take a "Flexcation," a trip that allows us to mix work and play. Thanks to the ability to work remotely and our kids' distance-learning schedule for the fall, we're planning a mid-week trip next month that will allow us to explore a new destination after clocking out for the day.

    We’re embracing off-season deals.

    With Labor Day no longer marking the end of our vacationing season, we're able to take advantage of nearby getaways that mark down their rates during the off season. For us in the Mountain West, that means visiting ski-town destinations when the leaves are falling rather than the snow. By saving money on that front, we're able to splurge a bit with our accommodations—so you can bet I search for houses that include a private hot tub for soaking in while enjoying the mountain views!

    Vacationing is a way to give back.

    If we've learned one thing this year, it's that life can change pretty quickly. That's given us a new appreciation for generous cancellation policies and transparent cleaning guidelines when booking trips. By seeing both of these things front and center in Vrbo listings along with reviews from fellow travelers, I feel confident when I hit the "book now" button.

    Beyond that, I know that booking a trip through Vrbo isn't only a gift to my family. On the other side of the transaction, there are vacation home owners and property managers who appreciate the income during these uncertain times. What's more, taking getaways allows us to support our local economy—even if it's just by ordering new takeout food to enjoy from our home away from home.

    While "looking ahead" doesn't feel as easy as it once did, I am confident that there will be a lot of drivable getaways in our future.
