Nope. Absolutely not.
You should read the book "Protecting the Gift" by Gavin DeBecker... in it, he talks about one of the best ways you can avoid having your children become the victim of sexual abuse (which, unfortunately, something like 1 in 3 girls are) is to not allow them to have male caregivers. Most people are abused by someone their mother trusts.
Not to cast aspersions on this boy -- he is probably a lovely young man. I just think it's a wise policy to have.
