Or WWYD - Inappropriate language

[Clandestino]

DD plays with a group of friends on the green everyday. One if them is a boy who is 5 or 6. He told her yesterday that a girl in his class told him she really likes him and asked him to rub her privates.
Now call me naive but kids that age shouldn't be familiar with this language or get that kind of proposition from anyone let alone their classmates, in my honest opinion.
As per DD, this boy loves to fib but again, not something you would expect a boy that age to talk about, at least I haven't heard any of the kind from DD and she couldn't keep a secret if her life depended on it and tells us everything, she can't help it.
Except for the talk with DD about the proposal and how inappropriate it is (done already), WWYD?
I'm torn between ignoring it or talk to the boy's parents.
It could be very innocent and kids that age are experimenting with their sexuality without knowing about it and they can experience arousal but shouldn't it be a task for the parents to explain that to their children and guide them through this sensitive topic?

If it happened at the school, I would be informing them, and let them deal with it.

I am certain at 5/6 my dc were not exploring their sexuality.

I would be giving him a wide berth.

April, kids that age can experience arousal and would sometimes rub their private parts on toys etc because it "feels good". There's nothing shameful or pervy about it but it's up to the parents to help them understand how to deal with it.

Report it to the school, they will then follow their safe guarding procedures (although, rightly, you won’t be told anything about what action they take)

I'm our safeguarding officer at school and I would absolutely want to know this

Thank you ladies, I will report it to school. I don't need to know any details about the follow up but I wanted to make sure I am doing the right thing.

Feel good factor isn't sexual arousal.
