A. hi mam ,first as mother's milk is best for a child ,I advise to use any good brand nipple shield like Babyhug brand nipple shield for this. mam , as your child having blue tongue ,I advise to Clean it after each feeding. and if your child feel discomfort ,it is better to consult your pediatrician for once
