Begin baby-proofing before bringing your infant home from the hospital. “Safety and preventing potential accidents are of the utmost importance,” said Dr. Alberto Del Pilar Jr., a family medicine physician in Oswego, New York. Ensure that your crib's mattress fits snugly and the distance between side rails meets standards set by the American Society for Testing and Material, with no spaces large enough to trap your infant's head. Keep nightlights 3 to 4 feet from your baby’s sleeping place and the curtains, to reduce chances of a fire. Baby-proofing your home is especially important once your baby starts to become mobile and interested in his surroundings, Del Pilar said.
