How to Choose the Best Pacifier. Today in the Lab we hear from Baby 411 author and pediatrician Ari Brown on the subject of choosing a pacifier for your baby. The AAP now recommends that all parents use a pacifier as a part of their Safe Sleep Guidelines to prevent SIDS. But which pacifier is right for you and your baby? Ari is joined by her favorite lactation consultant Linda Hill and she weighs in on the Great Binky Debate. She prefers a rounded shape to the nipple -- not flattened or flange shaped as this will cause abnormal breast feeding and potentially hurt mom. Weaning from a pacifier should happen at 4-6 months of age. Your local independent baby specialty store will have a good variety of pacifiers to choose from. Thanks to Baby's and Kid's 1st Furniture.
