Hi, R. -
We sound similar! My children are 5 (boy, August 2001), 3 (girl, December 2003), 24 months (boy, February 2005), and 6 months (boy, August 2006). Interested in a playdate? (Seriously!) I've been through all sorts of ups and downs in nursing my children, and I've definitely dealt with babies who suddenly didn't want to nurse anymore. Once they get used to the faster flow of a bottle, they get frustrated with the slower flow of the breast and they protest. I can only recommend that you try to eliminate all bottles if at all possible, and force your daughter to exclusively nurse until she gets used to it again. I planned to nurse my daughter for at least a year, but when she started taking bottles around 2 months old, she started refusing the breast and throwing a fit until I gave her a bottle. I gave up eventually and now I regret not trying harder to get her back to nursing. It will be hard but your daughter will eat if she is hungry, so I would really consider doing a big push for nursing and not giving bottles for a while.

PS I'm serious about the playdate!
