As we shift to warmer weather, the temperature of your house, whether or not you have an air conditioner, and the climate where you live all factor into your child’s sleep comfort. The American Academy of Pediatrics recommends a sleeping temperature between 68 and 72 degrees for safety. The right summer pajamas help, too.

Jennie Clarke, a certified sleep consultant from Good Night Sleep Site, shared some tips to keep babies and little ones sleeping comfortably in the spring and summer months. “If your home is on the warmer side of that range, you do want your baby sleeping in less or more lightweight clothing,” she said. “You can choose breathable fabrics, like cotton or cotton muslin. Avoid synthetic materials because they can trap heat.”
Clarke also recommended closing the blackout curtains earlier in the day to keep some of the heat out of the room and consider circulating the air with a fan. The best way to check your child’s sleeping temperature is to feel the back of their neck when they are sleeping.
We’ve rounded up some adorable (and breathable) summer pajama options, whether your baby, toddler, or little kid is sleeping in a room without AC—where you may opt for a short-sleeved onesie and a lightweight sleep sack—or breathable cotton or soft bamboo sleeper pajamas. Read on for our best summer pajama picks for babies, toddlers, and kids.
