More Milk, Please

So I'm convinced my breast milk production has decreased over the last several weeks. Emma sleeps so long at night, so she really only gets in about five feedings a day. In order to boost milk production and to help her gain weight, I've been nursing her pretty frequently during the day. Then before I go to bed at night, I pump, so that I can give her that bit of milk at her nighttime feeding the next night after nursing her. I think she's not getting enough mostly because she is so excited to polish off a 5oz bottle of milk AFTER nursing before bed. She kicks her legs and lunges after the bottle. Otherwise she is still sleeping great and acting normally, but I'm going to mention my concerns to the pediatrician at her 6 mo check coming up next week. And we can get a good weight recheck then too. We'll see!
