Just wanted to add that you can do this with other grains, too -- millet, amaranth, brown rice, etc. You don't need to limit yourself to "breakfast" grains. I don't know offhand how these grains compare nutritionally, but that'd be easy enough to research and you can also combine them.
Oh golly, here I go again on my SuperPorridge rant.
I was trying not to do it, but I just cain't hep mahself...anyhoo, the SuperPorridge idea, it's taken from Ruth Yaron's SuperBaby Food book, and I seem to blather on about it here every other week.
So you can search these forums and get more info, too. Suffice it to say, for now, that you can make really healthful cereal for your little ones, and stick all kinds of good-for-them stuff in there. I've been making DS's cereal since he was a wee bairn, and most days it's the only thing he'll reliably eat. Little does he know it's good for him! Murrrhahahaha!!!!
