A couple hours ago I had fed DD like I always do and after her bottle whilst trying to settle her she starting heaving and ended up throwing up. It was chunky... what's up with that? Should I change formulas? I am actually waiting for my pump to come in the mail as I am re lactating and she isn't latching and I'm not hand expressing enough for a full bottle.. She is on Similac Sensitive. Also she has been super fussy the last 2 weeks or so and the doc pretty much dismissed the fact she is inconsolable most of the time. Also waiting for gripe water to arrive. Ideas?
