So, at a year, I started giving my son one formula cup a day, then pumping his other daily "drinks" and nursing before bed and in the morning, so I didn't wean all the way until 18 months. Until he went then, I gave him alimentium formula, which is very expensive, but since I was pumping for daycare and in the evenings, it wasn't terrible, but it is best when they can't have milk, my son's tongue started swelling after the hives, so be careful (that's very rare, but can happen). I couldn't use soy, since he was hospitalized after getting soy formula when they spilled a breast milk bottle. So until he's a year and a half or so (maybe 2) I would stick with the expensive formula, or keeping pumping. After that, I'm not sure why you think rice milk is so bad, both my pediatrician and my pediatric allergist (since he had such dangerous and violent reactions to foods) told me to put him on enriched rice milk, original, not flavored. It has the fat and calories that need and the organic is good for them. I would talk to your doctor about rice milk, it's really not that bad, there is no scientific data suggesting a problem with it, like there is for soy milk.
