Hello all! Thanks for all of the advice--I have found this website very useful. I have been BF for 12 weeks now and want to introduce a bottle of formula just once/day to start out. Our baby has been taking 2 bottles/day of BM since I've been back to work. I thought if I introduced formula once/day, I would only have to pump at work twice. Any advice on how to go about doing this? Will I be able to combo feed without my supply drying up?
