my baby is 11 weeks and is breast feeding on demand. I also express so that my hubby and babysitter can feed her when I am out. for about 2.5 weeks now, she has been sucking down her 5oz bottles so fast, and wanting even more, maybe 8/9oz per feed. my hubby says I am overfeeding her.... in other words why does she eat/want so much??? and plus...I also seem to be pumping less. I used to wake up totally full in the morning and could pump 5oz or more easily, now I can only get 3oz. what can i do to pump more, I really don't want to be pumping at every feed 3/4 times a day! I am so confused...is my baby over fed? do I need to give her big bottles already? why does she eat so much, so fast?
