Keep Your Baby Safe and Comfortable in Hot Weather: Summer Tips for New Parents

How to Mother Your Baby in the Summer Heat (Without Losing Your Cool)

Hey there, mamas (and papas)!
Summer is officially in full swing, and while you may be dreaming of beach days and iced coffee, your baby? They just want to stay comfortable. Here is how to keep your baby safe and comfortable in the hot weather. The heat can make even the calmest newborn cranky, sweaty, and downright miserable — and let’s be honest, we’ve all been there too. But when it comes to keeping babies safe and comfy in hot weather, there are a few things every parent should know.

Why Temperature Control Matters for Babies

Here’s the deal: babies aren’t great at regulating their body temperature yet. They heat up faster than older kids and adults, and they can’t sweat efficiently to cool themselves down. That means they’re at greater risk for overheating — which can make them fussy at best and dangerously sick at worst.

Overheating has even been linked to increased risk of sleep-related concerns like SIDS (Sudden Infant Death Syndrome), especially in young babies. So while we might worry about keeping them warm in the winter, summer calls for just as much attention — only now, we’re working to keep them cool. Luckily, that doesn’t mean you need to blast the AC or buy fancy gear. A few smart strategies will do the trick.

Let’s dive in.

Babies and Water: Less Is More

It’s tempting to think your baby might need a little sippy of water on a hot day — but if your little one is under six months, don’t do it. Breastmilk or formula provides all the hydration they need. Offering water too early can mess with their electrolytes and fill their tiny stomachs with something that has no nutritional value. Stick with regular feeds and trust your instincts. Feed more often if your baby seems thirsty.

Sunscreen and Sun Exposure: Keep It Minimal and Smart

For babies under 6 months, sunscreen is a no-go. Their skin is just too sensitive for those chemicals — even the gentle ones. Instead, use shade to your advantage: wide-brimmed hats, stroller canopies, a muslin swaddle draped lightly over a carrier, or just staying indoors during peak sun (10 AM–4 PM). When your baby is old enough for sunscreen, go for mineral-based options and test a patch first.Bonus tip: you don’t need to bake your baby in the sun to get enough Vit D – that’s what Vitamin D drops are for.

Less Is More When Dressing Your Baby

This might be my favorite advice to give because it’s so counterintuitive to how we usually think: don’t overdress the baby. On a hot day, a simple cotton onesie or even just a diaper is perfectly fine. Layers trap heat. And that baby burrito blanket that looked adorable in the hospital? Let’s save it for fall.

Check your baby’s chest or back if you’re unsure — if they’re sweaty or warm to the touch, they’re too hot. Fussiness, flushed cheeks, and heat rashes are all signs your baby might need a wardrobe adjustment.

Babywearing in Summer? Yes, But Wisely.

You can absolutely still babywear in the summer — but you’ll need to be intentional about it. Choose breathable carriers made of mesh or linen, and avoid synthetic fabrics that trap heat. Dress yourself and your baby in light clothing, and take breaks in the shade or indoors. Keep their head uncovered and check their temperature often.

And while we’re at it: don’t forget to hydrate yourself. A dehydrated parent doesn’t make for a fun summer day.

A Quick Story From My Own (Sweaty) Summer Days

Years ago, I was at a July 4th cookout in Maryland, and one of the new moms there had her baby bundled up in a fleece sleeper because “he didn’t like to be cold.” I looked at her, looked at the 95° temp, and gently asked if I could peek under his blanket. That baby was sweaty, red, and wide-eyed like he was ready to file a complaint. We quickly swapped him into a onesie, offered a breastfeed, and plopped him in the shade with a damp cloth on his head. Ten minutes later? Sleeping like a champ. Sometimes we just need a little reminder: babies run warm, and simpler is usually better.

Summer with a baby doesn’t have to be a sweaty mess of trial and error. You’ve got this — and when in doubt, keep it simple: less clothing, more shade, and lots of love.
