As spring and summer settle in, kids and families look forward to spending more time outdoors, with more stroller walks, park days, and outdoor adventures on the horizon. But if you’ve just had a baby, warm weather brings a new set of questions around how to keep your newborn cool, comfortable, and safe while you enjoy the great weather.

To help new parents navigate summer with confidence, we talked to Dr. Cathryn Stamatos of our Glen Cove office, and put together some simple, practical tips focused on caring for your newborn in the heat. From safe outdoor time and sun protection to feeding tips and signs of dehydration, we hope this quick guide makes it a little easier to enjoy summer while keeping your baby safe and supported.

OUT AND ABOUT WITH BABY
When’s a good time for a walk with baby in summer?
Early morning or evening walks are a great way for babies to get fresh air and establish a calming routine. If the temperature climbs above 85°F or it’s very humid, it’s best to stay indoors, as heat can quickly overwhelm young infants.

Can babies enjoy the beach or pool?
Babies under 2 months are especially sensitive to heat and infection, so it’s best to avoid the beach or pool entirely at this age. After 2 months, short, shaded visits may be okay with caution, but babies should stay out of direct sun.

How can you drive safely with baby in the heat?
Keep the car cool, use sunshades, bring extra feeds, and never leave baby alone in a parked car, even briefly.

What helps prevent baby from getting overheated?
Dress them in lightweight, breathable clothing like cotton onesies or rompers; nothing too tight or layered. Skip hats and socks indoors, and choose soft fabrics that allow air to circulate.

SUN SAFETY
What’s the best way to protect babies from the sun?
Minimizing sun exposure is the best way to protect babies under 6 months of age. Shade, wide-brimmed hats, rash guard clothing, and lightweight long sleeves are also great for sun protection. Sunglasses are also sunscreen for baby’s eyes!

When should I start using sunscreen on my baby?
Sunscreen isn’t recommended for babies under 6 months. Instead, keep them fully shaded and covered with lightweight, protective clothing. After 6 months, a mineral based sunscreen of SPF 30 or higher can be used on small exposed areas like the face and hands.

COOL AND COMFY INDOORS
What’s a comfortable indoor temperature for babies in summer?
Keep the room between 68 and 72°F for comfort. A fan or air conditioner is fine to use, just avoid direct airflow on your baby, keep the air gentle, and dress them in light, breathable layers.

How should you dress your baby when it’s really hot?
Indoors, one light, breathable layer like a cotton onesie is usually enough. A good rule of thumb is to dress them in about the same number of layers that feels comfortable for you indoors.

If you’re going outside, baby needs a bit more protection. Add a wide-brim hat and loose, lightweight clothing that covers arms and legs to protect from the sun, while still keeping baby cool.

FEEDING IN WARM WEATHER
Should I feed my baby more often during hot weather?
Yes, babies often want smaller, more frequent feeds when it’s hot. Follow their cues and offer the breast or bottle regularly to keep them hydrated.

What if my baby isn’t eating as much in the heat?
It’s also common for babies to have a smaller appetite during hot weather. Keep offering feeds often, make sure they’re comfortable and cool, and watch for regular wet diapers to ensure they’re staying hydrated. You can always check in with your pediatrician if you’re unsure about feeding frequency.

HYDRATION TIPS
How can you keep your baby hydrated on hot days?
For babies under 6 months, breast milk or formula provides all the hydration they need, even in a heatwave. Just offer it more often if they seem thirsty.

What are some signs your baby might need more fluids?
Dry lips, fewer wet diapers, or a little extra fussiness can signal it’s time to offer a feed.

Can I give my baby water when it’s really hot?
More frequent breast or bottle feeds will keep your baby hydrated. Babies under 6 months don’t need water, even in hot weather. After this age, check in with your pediatrician about when and how to start offering small amounts.

When is it a good idea to check in with your pediatrician?
If your baby hasn’t had a wet diaper in 6 or more hours, seems very drowsy, or just doesn’t seem like themselves, call their pediatrician to check in.
