I a not a teacher so I have no training in this and this is why I am posting here. A child in my son's class (they have been friends for several years) is 'always talking about sex' (according to my Ds). Ds has mentioned this on a few occasions. He also said he looks at everyone when they are changing for PE. Yesterday, ds said his friend said something DISGUSTING. He didn't want to tell me, but I assumed he mentioned it because he wanted to talk about it so I asked him at bedtime when he's more relaxed. He asked "Would you rather suck Miss x's boobs or Miss y's boobs?" (both teachers in school).
I am not sure what to do about this. His mum is a TA in the school. Also, ds is due to go there for a sleepover on Sat (mum is helping us out) and I don't know what to do about it. Dh doesn't want him to go on the sleepover now (he doesn't actually know what has been said as he only got as far as the 'My friend is always talking about sex' bit).
I don't know what to do regarding the sleepover and regarding the comments, whether to approach mum or the school.
