Dd just told me that her friend at school confided in her that she had "sucked a boy's penis", and that he had "sucked her vulva and nipples". I didn't know how to react really. I kind of gently questioned to find out who this boy is. It turns out that it is (probably) either the girls step-brother or her dad's girlfriend's son (dd wasn't clear), and that he is kindergarten age. The girl is 8 and in grade 2. Dd wasn't sure why they decided to do that. Dd said that she would definitely not want to do that because pee comes out penises. Dd also said not to tell the girl's dad because the girl said he would be really mad if he found out.
Ok, so where do I go from here (if anywhere)? Is this pretty normal "playing dr" kind of stuff? My dd and her friend have done plenty of "I'll show you mine, you show me yours", but no touching as far as I know. Is it normal for kids to get the idea to put their mouths on other people's privates?
Anyway, any thoughts appreciated.
