Here's a tip from author Ellen Notbohm's October autism newsletter:
"A group called Allergy Moms publishes an engagingly written e-newsletter featuring the latest allergy-free products, advice and information. If your child is on any kind of "-free" diet (wheat, casein, nuts, eggs, etc.), you will find much that is helpful, plus some fun promotional stuff. I get a lot of newsletters and like you, don't have time to read all of them but after several issues, this one impresses me. Please visit www.allergymoms.com and click the newsletter sign-up button."
