Ok so baby girl is now 5 months old,. I'm nursing her exclusively when I'm with her, but I work like 37 hours a week. I know the ounce an hour rule for exclusively breastfeed babies, but what about babies that recieve formula during the day. She drinks mostly formula during the day, I've seen that with formula fed babies the amount they drink should be increased but with breast feed babies it shouldn't. What should I do should I tell them to stop feeding her so much formula or just let it go because she is getting mostly formula during the day and nursing the rest of the time?
