I have a 3 1/2 week old daughter which I've been breastfeeding since she was born. We complimented with formula the first 4 days because she was little (5lbs) due to an early labor. She has been going through a "growth spurt" for almost a week now, which doesn't leave me much time for anything besides breast feed her. But what worries me is that she is starting to eat for 5 to 7 minutes, when she used to do 15-20minutes. Then she gets all fussy and wants to eat again, or at least thats what I think so. So instead of eating every 2 hrs or every 1 hr or even every 45 min, she is like constantly eating: eats-fuss-eats-seems like is falling asleep-fuss-eats, etc, and sometimes this can happen for over 2 hours in a row, making my nipples really sore, right when they were getting to the point it was no painful anymore. This is really frustrating and is making me want to throw the towel. I don't feel like I'm enjoying breastfeeding and she probably feels that from me. And it makes me feel like a terrible mother. I just want to know if its normal, or if she is disliking my milk or if she is actually getting nourished. She seems to be gaining weight and has wet and soiled diapers all the time. But why is she getting so fussy and uneasy?
Also she doesn't seem to fall asleep if is not in my arms, like if I put her on her crib or bassinet she wakes up. Is that normal or ok? Its just really hard then to "sleeps when she sleeps", and i'm super tired by night.
