My DD (8) has just been to a party of a boy in her class. She told me afterwards they'd been playing in the boy's bedroom filming themselves saying rude ryhmes and songs and putting it in YouTube. The rhymes were the sort that 8 year olds do tend to pass round in the playground, but sexual rather than just lavatorial humour, most of it over their heads I think. I'm a bit worried about this, but can't quite seem to come up with any clear arguments to her as to why she shouldn't be doing this. She's pointed out that not many people are likely to find their clips on YouTube, but I still feel uncomfortable about it.
She's new in the school and I don't know this child or his parents at all, so don't really feel I can speak to them about it.
Am I being over-anxious, or should I tell her firmly this isn't allowed? And how would I police it if I did? (She doesn't have an internet connection in her room at home, but many of her friends do).
