Great job! Breastfeeding that long is hard work!
I weaned my first at 27 months when he was down to a couple feedings a day. He too never took a bottle. He wouldn't even take a sippy cup. He would nurse or drink from a regular cup only. And he would only drink water or breastmilk. I think maybe I had an advantage because of his age. He understood me pretty well.
My mother-in-law was down for Thanksgiving, so we had a pretty busy schedule. One day we left early in the morning and didn't return home until well after dark. We went to a park, coffee, lunch and diner. My son didn't ask to nurse, so I didn't offer. He fell asleep in the car. The next morning, I jumped up excitedly and offered imediate distraction. He didn't ask until that evening (I kept him up a little later than normal). I told him "not tonight, how about a book?". He was so tired and thrilled at the new book, he agreed and passed out. He didn't protest until the 3rd day of no breastfeeding. There was only a tear or two, but I held him until he fell asleep for the next week or so. I made sure to replace his "boob" time, with cuddle time.
Make sure that there's nothing big going on her life right now. Breastfeeding is a real comfort and weaning is best when the rest of the childs life is normal. You could also just cut down to one feeding a day, until she's a bit older. I sometime wish I had done that instead of weaning. Also, I recomend not letting her see your breasts until a few weeks after you wean. My best friend gave me this advise and I really think it helped.
I hope you do what's right for you and your daughter...Good Luck!!!
