Some babies have difficulty sleeping flat on their backs, which is recommended by the American Academy of Pediatrics. This sleeping difficulty may be caused by colic or acid reflux. But it is not recommended to place a pillow or any other fluffy object to help raise the baby's head. Instead, parents can raise the head of the bassinet to help the baby sleep better, while keeping him on his back.
Remove the mattress from the bassinet and place it aside.
Fold one or two towels or receiving blankets in half. Roll them into tight rolls.
Position the towels or receiving blankets at the head of the bassinet where the baby's head will lie.
Replace the bassinet mattress. Make sure there are no gaps between the mattress and the side of the bassinet.
Avoid placing your baby to sleep on her stomach. While she may sleep better that way, it increases the risk of sudden infant death syndrome, or SIDS. If you cannot get your baby to sleep, speak to your pediatrician about options.
