Hives in the Church Nursery

Owen had a reaction in the church nursery. I think it is because a child brought a pastry into the play area. I asked that the child finish his breakfast in a different place, and the volunteer gave me a cross look. About 30 minutes later, the same volunteer called me out of the service because Owen broke out in hives. I felt so bad for Owen, but I felt justified in my earlier request to have the boy eat his pastry somewhere else. I didn't give Owen benadryl, because it wasn't that bad. His face remained red and itchy for about 5 hours.
