This is my 3rd child I have EBF, but the first time that I will be returning to work and will be expressing. I am trying to figure out how much I should need to leave with his daycare provider, and will he still want to nurse when I get home? I am heartbroken, I am afraid he is going to want to continue on the bottle as it may be easier.
I also returned to work when my DD was 6 weeks old, and I have not had a problem with her having any nipple confusion. She is still very much a booby baby and sometimes resists the bottle when I gone. So try not to worry.
I'm not sure what your hours will be but this is how I do it. I breastfeed her at 7:30am before I leave for work. Then she has a bottle of EBM every 3 hours while I'm working (usually 9:30, 12:30. 3:30) Then I nurse on demand from the time I get home and all night, and I still nurse on demand on the weekend. At six weeks she was taking 4ozs a feed, so I packed 12oz a day. At 16 weeks she started taking 5ozs per feed (15 ozs per day)
At first was I was having trouble pumping enough at work, so I also pumped at night after she went to bed. I started taking More Milk Plus (bought from Amazon) and that upped by supply enough to just be able to pump enough at work.
Good luck and try not to worry. I'm sure he will still be a booby baby!
