Hi..My 4 months old daughter is having nipple confusion. i generally give her 90 ml formula once a day and rest all breast feed. initially there was no problem. She use to take bottle nipple very easily.But from past 3 4 weeks, every time i give her bottle feed, she doesnt latch bottle nipple properly. it touches her tongue and she makes puky sound and gets pukish ..if i try to much ..she pukes.. its not the problem of formula,neither its the angle in which i hold the bottle..i have tried holding bottle in all angles. i have tried lifting her head while feeding. once the sucking/latching starts correctly ,she takes the whole feed but problem is she is not able to latch . Mostly its the shape/size of the silicon nipple which touches her tongue ans makes her puke. i am using this nipple https://fstcry.in/Z38Cbnna11mPZTt1A . please tell me which nipple i should use.
