After 1 early success she's not interested. She'll refuse it or just chew on the nipple. She won't drink even if a little milk comes out of the bottle. After a while she'll start to cry until I give her the breast. I've tried Medela, Dr. Brown, BornFree bottles at different times so far. Today I'll try Avent and try again The First Years bottle... forget the name. So frustrating... I don't know what to do! I have about 2 weeks before I go to an all day training class I registered for.
