When the temperatures rise, keeping your little one cool, safe, and comfortable at night becomes a top priority. We know that peaceful summer sleep starts with the right essentials. That’s why we’ve curated this guide to help you choose breathable, cozy sleepwear for your baby—so everyone sleeps a little easier.
Whether you're in sunny California, humid Florida, or anywhere warm and breezy, these tips (and must-have Pehr pieces!) are here to help.
Why Warm Weather Sleepwear Matters for Babies
Babies aren’t able to regulate their body temperature as well as adults, which means overheating can be a real concern. The American Academy of Pediatrics recommends dressing your baby in one more layer than you would wear yourself—and in hot weather, that may mean just a one piece or a light sleepsack.
Choosing natural, breathable materials is key. That’s why all of our sleepwear at Pehr is made from 100% organic cotton—gentle on baby’s skin and perfect for warmer nights.
Signs Your Baby Might Be Too Hot at Night
Not sure if your baby is too warm while sleeping? Here are a few things to look out for:
-
Sweaty neck or damp hair
-
Flushed cheeks
-
Fast breathing
-
Restlessness or frequent waking
If you notice these signs, it might be time to switch to lighter layers.

Quick Warm-Weather Sleep Tips for Parents
-
Keep the nursery cool: Aim for 68–72°F (20–22°C). Use a fan or AC to circulate air (just not pointed directly at baby).
-
Skip the socks: Bare feet help babies regulate heat naturally.
-
Use blackout curtains: Help maintain a consistent sleep schedule, especially during longer daylight hours.
-
Hydration matters: For nursing or bottle-fed babies, offer feeds more frequently in the heat.
