My 19mo just started Childcare 2 days a week and they asked me if he had had peanut butter yet as it was a potential lunch option and I said no, but know I am worried that he will grab some other kids and that it is time I figured out if he has an allergy or not. He does not appear allergic to anything else although he has had bad eczema when he was younger and still has quite sensitive skin. TIA
