Today my ds nearly 3 asked for a snog, he opened his mouth and tried to kiss me.When I told him it was wrong and you dont kiss like that he told me does it,i asked what else does and he started sticking his tongue in and out. is a 6 yr old girl whose house he stays in sometimes, she is a relative.Now im worried do I approach her mum or is it just playing.I am a regular poster just posting under a different name.
