I am absolutley mortified. My son has said some very inappropriate sexual things in nursery and I don't know where the hell it has come from. What do I do? He did it first yesterday and I explained we don't say or do things like that. And now again today. His father and I are not together and I do not have a partner, I do not watch anything but childrens channels when he is up so nothing from tv, he has no older siblings he would pick it up from. I'm so embarassed!
