I need help weaning!

I have nursed two babies, so you'd think I know what I'm doing right now. But as it turns out- I'm clueless. With Mowgli, I had a raging infection and had to stop cold turkey at around 9 months, so there was no weaning at all. He was already taking the bottle well and the 2 day transition was easy as pie.

This time it's different. So, Pocahontas is 11 months old and starting to wean. She doesn't really take a bottle- she mostly plays with sippy cups (drinking bits here and there) and mainly loves water from a normal cup witha  straw. I am still her main source of fluids. But things are changing. Some days she nurses 4 times a day, sometimes twice a day, other days she wants to nurse 5-6 times a day. She's also getting tooth upon tooth right now and is biting, biting, BITING! Ouch! I am struggling with my milk supply being painfully in flux, soreness from her teeth, the heartache of knowing our special close time is almost over, and elation at knowing that a little more freedom is just around the corner. I would love some tips about how to do this well. Moms out there- help! What do you think? Send me your tips.
