My son tells me that there are three or four boys who play together in the schoolyard. They touch each others' privates. My son tells me they have been found out by lunch/recess aids who have done nothing about it.
There is one boy in particular who is the instigator. When the others play w/o him, this does not happen. ( I have long since discontinued playdates with this one boy.)
My son does not participate but does watch his friends. We have had many talks about what is private and what is shared.
School is over in one week. (these are kindergarten children)
what would you do?
