my 2 month old baby is troubling me a lot for getting used to formula and bottle feeding. whenever I try to feed her using a bottle, she doesn't suckle and cries a lot. For few days after birth, she use to drink formula milk from bottle very well until she got used to breast milk. after she got used to breast milk, I stopped giving her formula milk and now after 1 month when my milk is not sufficient, she's not drinking from bottle.
