Hi B.,
My almost four year old daughter has food allergies, including a peanut allergy. Believe it or not, Wal-Mart's brand Great Value has a soy butter that's peanut free. By law, I believe manufacturers must state what allergens are in a product plus whether the product is manufactured on machines that process other allergens. The only allergy warning on the label is "contains soybeans."
My daughter likes the soy butter a lot and I hope your son likes it as well. If that brand doesn't float his boat, try a natural food store, they carry a few different peanut butter alternatives.
If you're looking to meet other SAHMs, I agree w/ Kari S., the MOMS Club is a wonderful support group with playgroups, Mom's Night Out, family activities, seasonal parties, etc. I have been a member of the Clearwater chapter since my daughter was 4 months old and we have made life long friends. You can go to http://www.momsclub.org/ and find a chapter near you.
Best of luck,
J.
