DS 1 was FF from the get go and did it like a champ until his magical switch over to regular milk at like 11 months or so. However... Ean, my little ornery jitter bug has been uber attached to BFing. He rejected solids at first but finally has gotten on the bandwagon. He just now has gotten where he will sort of deign to take some sips out of his sippy cup (flat out rejected a bottle). He HATES formula though and will not drink it. I tried to wean him a month or so ago and he went an entire day without drinking (I thought eventually he would cave, but I ended up being the one who caved and put him back to breast after 10 hours). Needless to say, I don't feel comfortable with the fact that he seems to be self weaning now when I know he hates formula. Any advice? I've got no idea what to do but feel I should be supplementing now because he has backed off a ton.
