When I weaned my dd she was 12m and 2d old. When she was 11m she was at 2 feedings a day am and pm. I just cut one of them because it seemed she didn't need the pm one anymore. For one month she was at 1 feeding in the am. I cut that one right after she turned one. It wasn't helping her to fall back to sleep and she was playing so she was showing signs of not needing it.
I didn't replace it with anything but just moved her to sippys of milk during the day, though you could replace it with something if you wanted to. I was really nervous about weaning, too. But, if your child is showing you signs of being ready it will all work out nicely. It did for me and it will for you too. :) I know it's scary, though.
But, by 12 m I was ready and nutritionally it's just fine to wean at that age. It's my personal opinion that there's not a whole lot of value to it after that age except for bonding.
Good luck!

I've been wondering the same think. My daughter is 10 1/2 months old and the pediatrician told us that she should be off the bottle by 12 months. She primarily eats solids, but still gets a few small bottles a day. I also realized over the weekend that the bottle she was getting before bed, didn't put her to sleep the way it use to. Should I just do away with it, or is it too soon to start weaning?

Are you weaning only b/c of the biting? She is probably biting due to teething pain. If you try a frozen washcloth or cold teething ring just before nursing it will help tremendously.

You will want to replace each nursing session with a substitute for now until she gradually cuts back herself.

Keep in mind that some babies still have a need to suck and if you take away the bottle they may rely more heavily on the pacifier.
