I have a friend works in childcare and says they are are seeing some very concerning behaviour.
Like 4 yo boys trying to simulate sex in the playground and simulating adult male masturbation techniques.
It's become a problem for them and, of course, with aggressive parents who won't hear a word of warning about their kids behaviour, the teachers can't discuss with the parents and have to keep a careful supervisory eye out ...not just for falling injuries and the like and now sexual interference from their playmates
At seminars they are saying that these parents are letting the kids watch the porn with them and thats how they are apparently picking up this behaviour.
How sad that children that young are being introduced and exposed.
