<<Disclaimer: Verify this information before applying it to your situation.>> Well, it looks like there's a big market out there for a good Cheerios substitute, but, unfortunately, none appears to exist. My thanks to everyone who wrote to me--I didn't have time to answer the letters personally, but I appreciated your kindness. There were quite a few alternative breakfast cereal suggestions: while my son and I have already tried almost all of them, I'll list them for those who might be interested. None of them is Cheerios-like, though, except for a health food version of Cheerios one person suggested, which uses oats (something I haven't introduced into my son's diet yet) and which can, apparently, be found at Whole Foods. The others, in no particular order, are: Erewhon's Poppets, Nature's Path's Honey'd Corn Flakes, Pacific Grain's Nutty Rice, Rice Crunch 'ems, Aztec Cereal, Corn Pops (some people have a reaction to these, though), New Morning's Cocoa Krispies, U.S. Mills' Cornfetti (also has oat flour), and Malt-o-Meal's Dyno-bites (fruity and cocoa krispies). I'm not making any claims for any of these cereals, just passing on others' suggestions. My thanks again to everyone who wrote. Claire
