So this is my first time posting my daughter is three weeks she's been having some issues gaining weight she only gained back her birthweight last week. The pediatrician has been feeding her I'm pumping after and I'm supplementing after feedings so basically I just have things attached to my boobs all day and I sleep ok and she sleeps ok too. We are now supplementing both day and night usually it is a bottle of an ounce half formula half breastmilk. My husband went back to work after the first week which is fine but it gets kind of old being home with someone who can't talk to you. I love her but I feel like like breast-feeding is taking more effort than it should. When I put by the end of the day I have around four sometimes 5 oz from pumping after she eats. I just hope when we go back on Thursday which we've been to the doctor every week doing weight checks this time we have a real appointment I hope that she started gaining and that maybe we're on the up and up. Just feel drained and I know things will get better just feel overwhelmed sometimes.
