My 3 1/2 month old daughter, Lily, is exclusively breastfed. I work 4 days a week and pump diligently; we are separated for about 11 hours 3 of those days. I send 4-4oz bottles to her daycare, but often have one left. Of those bottles, she rarely finishes any of them and often leaves 1-2 ounces. When I come home, she nurses every hour until bed time and wakes about 2 times during the night. I love nursing her at night and don't mind doing it that often since it allows me to reconnect with her, but I want to make sure she is getting all the nourishment she needs. She has plenty of wet diapers during the day, and a poop at least once a day (this has been the norm since she was 6 weeks). She was gaining 1/2 lb every week until for 8 weeks, but when I gradually started back to work, she only gained 12 ozs. in a 4 week period. The pediatrician told me she should be taking 6 ozs at a feeding (we can't even get her to finish 4 ozs!)
Lily is my first child, so I am new at this, but is this normal? Should I be concerned?
