Our 2 yr old DGS has a peanut allergy and I am thinking I should get him a medical alert tag just in case, at least before his b-day trip. He is good about asking everyone if they have checked the label but I have this nightmare of him being lost and a CM giving him a uncrustable or something while they find us and him taking it. OK.. I am overboard but what do you all do?? Neckace or braclet?? Any good online sites???
