When can my baby sleep with a blanket or pillow?
Keep blankets and pillows out of the sleep space until at least 12 months, and most experts say pillows specifically should wait until age 2.
Before these ages, loose bedding raises the risk of suffocation, entrapment, and SIDS.
Strong
Based on AAP national guidelines and their technical report reviewing the supporting evidence, not a single trial but a comprehensive evidence-based policy.
What the evidence says
For babies under 1 year, the American Academy of Pediatrics says to keep the crib completely clear of loose blankets, quilts, comforters and pillows. Their guidance states that soft objects like pillows and blankets should be kept out of the infant's sleep space, along with stuffed toys and bumpers.
If you're worried about your baby being cold, dress them in an extra layer or use a wearable blanket (sleep sack) instead of loose bedding. Guidance also warns against weighted blankets or sleepers for infants.
After the first birthday, risk drops. Official guidance notes that while there's no research pinpointing an exact 100% safe age, most experts agree these objects pose little risk to healthy babies after 12 months of age.
For pillows specifically, one AAP-affiliated source advises waiting even longer, recommending not giving a child a pillow until age 2, and making sure it's small and firm when introduced. So a safe, guideline-backed approach is: no loose blankets or pillows before 12 months, and hold off on a pillow until closer to age 2.
