My newborn daughter (3 weeks old) gets really fussy when nursing, particularly in the evenings. She'll show signs of hunger (rooting for the breast, mouth open etc) and will latch on to my breast and suck hungrily. However, after a minute or so she'll stop and push away from me and the breast and start a loud crying. Her face will turn red and she'll arch her back , throw back her head with her legs and flail her arms and legs about, while I'm thinking, "????????"" At some point I usually coax her back onto the breast but she'll do the same thing - latch on hungrily again, suck hungrily, and then pull away and start screaming. It's really frustrating because I can't figure out why she's upset. Sometimes I think she has gas and needs to be burped, but even when she does belch sometimes she goes back to crying. I do feel as if she's getting enough milk - because when she sucks I can see the milk around the corners of her mouth, and sometimes when she pulls away from the breast I can see the milk trickling down her chin. I was reading online about overactive letdown - but I don't think that's the problem either, because I don't have any problems with excessive leakage/spraying, and baby doesn't seem to be gulping or struggling to keep up with the flow when she's being fed. I don't know if she's just really hungry or impatient....sometimes when I get her back on the breasts she sucks voraciously...but then, why would she pull away and cry if she's hungry? I really can't figure it out. Does anyone have any ideas as to what might be going on? Does anyone else's newborns do this?
