Have you considered going to a LLL meeting? Most of the ones I've been to have had a lot of mothers with multiple kids who have experience with weaning. The nice thing about a breastfeeding support group is that their more likely to have nursed the full year and have experience weaning a toddler. Weaning a toddler is SO different from weaning a baby, isn't it?!
You can find local groups online:

Weaning is such a personal thing. It's hard to know what might work for a toddler I've never met. You might find this site helpful, though:

Also, try breastfeeding message boards, too. You might get more experience with weaning a child with a personality like your daughter's. lol If you just do a search on breastfeeding message boards, you'll find a bunch.
This place is great, but why not use all your resources, right?
