Hi H. -
My situation was similar to yours - I was ready to stop nursing (although I was very conflicted about it), but my daughter showed no signs of self-weaning. So at 21 months, we started preparing for her 2 yr birthday, when all the milk (mimi is what she called it) would be gone, because she was such a big girl she had drank it all. We worked down to two nurses a day--morning and bedtime--and then just one in the morning by 23 months. Every nurse we would talk about how when she turned 2 the mimi would be gone, making it a good thing because she was going to be a big girl at age 2. We talked about how her birthday party would also be a "no more mimi" party, etc., building it up to be a good thing. The morning of her 2nd birthday came, we had our last nurse, and the following few days were a bit rough in the mornings--we had to break the normal routine by avoiding the situation we used to nurse, ie bringing her in our bed after she work up. I or my husband would get up and play with her, not snuggle in our bed like usual, and when she asked for mimi, remind her she had drank it all because she was a big girl. After a week we could return to our snuggle routine in bed without mimi. A year later (she will be 3 in a few weeks), she still periodically asks to "drink mimi," which makes me feel horrible, but we talk about how she is a big girl and drank all the mimi. She gets over it, and the requests for mimi are fewer and fewer as she gets older. Anyway, the things I think that helped the most was the preparation, giving her a few months to work into the idea, positive reinforcement of being a "big girl" (so big that she drank up all of mommy's mimi!), slowly moving to one nurse a day, avoiding the typical morning nursing situation, and lots of love and snuggles at all times.
Good luck!
