My 3wk old is most likely going through a growth spurt at the moment. Yesterday she ate constantly, and she usually cluster feeds in the evenings between 6-10pm. Today she's been sleeping a bit more than usual, and while she hasn't been eating as many times, she has been eating for longer. Hope that made sense. Anyone else have this happen? I've been a bit engorged today from her not eating as much. Her output is fine - plenty of wet/dirty diapers and when she wakes up she's very much alert and interested in the world around her. Another thing - should I be pumping when she usually eats or only if I get very engorged?
