I have a boy whose mother is allergic to peanuts so she is unsure if her son is or not. I've had him since he was a year old and he's almost 3 now. When he was 1, he was in a high chair so I allowed other children to have peanut products which his mother was aware of. I was very anal about making sure the table and children were cleaned before this boy could come down from the high chair. Since he started eating at the table with the other children, I have become a nut free daycare. If a parent informed me that her child has a life threatening nut allergy, then I would have to tell them that I couldn't accept them into the daycare.
