The nurse from Health Centre said that my baby doesn't open her mouth big enough for BF, that may affect her drinking. She may need to suck more times for the same amount of milk as compare to if she opens her mouth widely because less milk come out with her 'small' mouth. That is my fault to train her not so good as from newborn, she has already made it as a habit. I tried to correct her, but it's a bit difficult to change it as she already used to for 6 weeks. At this moment, her weight gained quite good with enough wet diapers, should I insist to correct her to open her mouth widely? Pls give me some comment.
