#asktheexperts My baby is 24 days old n I am using nipple shield to breast feed her as directed by my paediatrician so till what period of time can I use it?

A. hi dear The newborn nipple should be the perfect size for your newborn, unless, like we mentioned above, if you have a premie who needs a little more time and can't handle the flow, it's best to switch to a slow flow size zero. Most regular newborn nipples have the size 1 on them.
