My DC won't open her mouth sufficiently wide to get enough breast into her mouth to feed properly. She is feeding on just the nipple rather than nipple and surround. As a result she hasn't been putting weight on (she hasn't lost it either) but the consultant has decided the way to go with formula through a NGT. Any tips on how to get her to open her mouth a lot wider? I've big breasts and the breastfeeding midwife said my nipples are "on the large side".
