You may find yourself wondering if your baby can sleep on his stomach, especially if he appears to be more comfortable that way. To prevent Sudden Infant Death Syndrome, or SIDS, which remains a threat until your baby is 12 months of age, it is best for her to sleep on her back, instead of her stomach.
