My daughter is 21 days old and for the past couple of days, her eating habits have been driving me crazy. She wants to eat all the time, especially in the evening. The other night, I spent from 8 p.m. until 2 a.m. nursing her, with only a few breaks of no more than 30 minutes in-between. When she's at the breast, she is fussing a lot, violently pulling away from my nipple (ouch!), then eagerly searching for it again. I know she's not eating the whole time, a lot of it is just suckling, but if I take her off the breast, she will immediately want back on. I've tried a pacifier, but she refuses to take it. The only way I could finally get her to go to sleep was by feeding her a bottle of expressed milk (I didn't really want to introduce a bottle this early, but they had already given her supplementary feedings with formula at the hospital because she was dehydrated from a fever.) Before that, we were doing really well, no problems, and she was even sleeping through the night! My LC has mentioned that she's probably going through a growth spurt, but on the Internet, I've found many descriptions of overabundant milk supply/overactive letdown that fit our situation to the dot. I am leaking a lot of breast milk even when I'm not feeding her. So now I'm confused whether I should try to decrease my milk supply to regulate the overabundance, or let things go naturally to feed her growth spurt needs. I'm also not sure if it is a good idea for me to pump breast milk. I'd like to build up a supply, but I don't want to make my breasts produce even more milk if it's already too much. Anybody have any advice?
