The ideal room temperature for baby sleep is 68–72°F, according to the American Academy of Pediatrics (AAP). This range helps babies stay comfortable without getting too cold or warm overnight.

Sleep experts generally recommend keeping your baby's room slightly cool rather than too warm, since overheating can be a risk factor for SIDS.

If your baby's room falls somewhere in that temperature range, you're in a good place. From there, focus on breathable sleepwear and adjust layers based on the temperature in the room.
