My baby won't eat, so she won't sleep. Also isn't gaining weight properly. The ped said she's seen this in 4-6 months, but not 3. She turns away from breast and is fussy while eating, but not that I am trying to pump and bottle her, similar is happeneing with the bottle. She just won't take it for very long. Then she tends to spit up more with the bottle too. :(  anyone have advice? Heartbreaking and I am sooooo tired.
