njbeachgirl, I was in the same boat. DS1 self-weaned with no protest when my milk supply dropped at about 25 weeks pregnant.
He was 13 months old and he was completely unfazed by it, I think because the milk had started to turn to colostrum and he simply didn't like the taste anymore.
We tried organic goat milk for about a day, but I did a bunch of research on MDC and elsewhere and decided that it wasn't as nutritionally balanced or as optimal as I would like, so we started using the Baby's Only Organic Toddler Formula
. It's been great for us and DS likes it. (YKWIM--it's as good as any formula can be--not my preference by any means, but a necessity in our situation.) We also use the Born Free glass bottles (no phthalates or bisphenol-A, unlike Dr. Brown's). We're planning on keeping him on it until he's at least 2... He does nurse very ocassionally since his brother was born, but isn't all that into it.
It's designed for babies 12 mos+. It is a bit pricey--about $9 a can and a can lasted us about 2-3 days when he was your LO's age-- but you can order it by the case at your natural foods co-op and get a discount, plus for every 24 proofs of purchase you send in, you get certificates for 2 free cans, which is a pretty good deal. After our 15% co-op members case discount, I think 2 cases (12 cans total) came to about $100 and lasted us a month back then, longer now.
Good luck, mama! I know how hard it can be to have to quit nursing your LO long before you would have liked to
