bfing...and weight loss

well i had my ds via c-section on March 5th, and ive been bfing. once i became active again i noticed the lbs dropping very quickly. less than 3 weeks after delivery, and im back at my prepregnancy weight(i gained 33lbs while preggo). im wondering how safe this is. on top of it all, i have no appetite. i take my prenatal pills, but im wondering if thats ok for the baby? he had a 2 week check up and he weighed a whole pound more from his weight when he was discharged, so im sure he's eating properly. in fact the dr mentioned that 1lb in 2 weeks may be too much gained.
i know its common to lose weight while bfing, but how fast, and how much is normal? can my lack of appetite cause concern beings that im bfing? his ped didnt seem too concerned, she just gave me a RX for multivitamins for him. can anyone share some experiences???
also what is the normal weight gain for new borns? like how much lbs should be put on by 1 month old? im wondering why his ped. said 1lb in 2weeks is too much.

NO such thing as too much weight gain for a nursing baby, shame on your doc for saying such a thing.

You really do need to eat something every few hours. I was really fond of Boost nutritional supplement shakes for when my appetite was low, which was often during the first few months PP.

I always lost my pregnancy weight super fast. My first gained over 2 lbs in 10 days, he left the hospital at 7 lbs 15 ounces at 2 days old, at his checkup at 12 days old, he was 10lbs 4 ounces and continued to gain quickly.
