I didn't BF my first, so I don't really know this. I am planning to BF exclusively when she's a newborn, but I will have to go back to work after 12 weeks. I don't know if I will pump, how much time I will actually have in the work day to do it.But I still want to BF sometimes, as formula is so expensive, and I know it is healthier. So can she eat formula during the day and then BF at home mornings, evenings and weekends? Or do you need to be BF'ing longer and have a better established milk supply before you can switch. How does this work? Any advice about BFing while working or sgoing to school or whatever is appreciated!
