Hi I have a 3 1/2 month old daughter who up till two weeks ago slept through the night and ate pretty well. Now she isn't interested in breastfeeding. When I feed her she will stop and look at me and smile (which I love!) then go back to eating then look at me again. Or she will push off the chair or whatever is by her feet, my arm, the wall anything. To top it off she isn't sleeping, she wakes up at 3:30 and won't go back to sleep and will then take a 2-3 morning nap and stay up until 9:30. I was giving her formula once a day and she takes it fine from a bottle. Please help I love her but don't know what to do and if I should switch to formula permanent or how to help her thanks!
