We've decided to introduce a bottle of pumped milk once a day for a variety of reasons (my yoga class, DH bonding, occasional drink, etc). I was having difficulty pumping enough so we got some formula from the hospital to add to it for a bottle. She initially hated the bottle and refused it, then she'd take a little once we started mixing it but not enough for a full feeding (an once or 2 tops). We finally found a bottle/nipple she'll take but she still won't take straight BM. 50/50 mix of BM and Alimentium is the most she'll take. My plan had been to move toward bottles of pumped milk around 6 months with continued evening and night BFing. I won't be able to do that if she won't take the BM in a bottle.
