What should my newborn wear to sleep?
Choose sleep clothing that keeps loose blankets out of the sleep space, and check your baby for signs of overheating.
The short answer
The CDC and AAP recommend keeping loose bedding out of an infant's sleep space. The AAP suggests, in general, dressing a baby in one layer more than an adult would wear in the same room. Avoid overheating and weighted products.
Use sleep clothing instead of loose covers
The CDC and American Academy of Pediatrics recommend a clear sleep space without loose blankets, pillows or soft objects. Sleep clothing or a correctly sized wearable blanket can provide warmth without adding a loose cover to the crib or bassinet.
The AAP's one more layer suggestion is a general starting point, not a precise formula for every room, garment or baby. Consider the room and clothing together, and follow product instructions and your midwife or doctor's advice for a baby with special health needs.
Watch for signs of overheating
The CDC notes that an infant shouldn’t get too hot. The AAP lists sweating, damp hair, flushed cheeks, heat rash or rapid breathing as possible signs of overheating. If you’re concerned about your baby's temperature or condition, contact a health professional.
Don’t use weighted blankets, weighted sleepers or weighted swaddles for an infant. Keep the baby's head uncovered during sleep and place them on their back on a firm, flat surface.
Keep advice specific to the product and baby
Sleep products can fit differently, so check the manufacturer's size and use instructions. Ask your care team how to dress a baby who was born early, has a health condition or needs extra temperature monitoring.
