What kind of reaction does she have in the sense is it something considered life threatening or just something annoying she may have to learn to put up with. I know that sounds bad but it may be something that you won't be able to protect her from coming into contact with unless you go the nanny route. Is she expected to outgrow the reaction. I have had kids that would break out in a rash on their hands when touching certain things but that is as far as it went. The rash would go away over the next hour or two. With one child it was milk - she would eat cereal that had been dipped in milk - ie just enough milk added and left to coat the cereal and soften but not make it soggy. For awhile she was fine but over the next couple months she started getting a rash on her hands when doing this. She was tested for allergies and it all came up negative. Doctor said it was just the sensitivity degree of her skin and not to worry about it because the rest of her body wasn't having a reaction. She outgrew it. Not saying that applies to your child but always nice when a child does outgrow an allergy and you don't need to worry about it anymore. How much contact does your child need before they have a reaction? Are you sure that accidental contact from saliva for example is an issue or just milk direct? Would a daycare where the children eat only at the table, washed after be ok?
