DS is going through a real phase of being fascinated with private parts and also with all things toilet related! He talks about willies, boobies and noonies all the time, as well as weeing and pooing. He always wants to see or touch mummy and daddy's private parts (e.g. "I want to pull your willy Daddy"!!). He thinks it's very funny to pull down his pants and show people his willy/bottom.
I know that's all perfectly normal but want to guage what people think is an appropriate response / way to teach him.
So far we have said to him: willies, boobies, noonies and bottoms are private. That means we don't touch other peoples', we don't get them out in public and we don't let other people touch ours (unless mummy/daddy etc helping DS wash in the bath / wiping his bottom etc).
Basically I don't want to create taboos and make him think it's all dirty / disgusting etc; but neither do I want him to make embarrassing and inappropriate comments in public and certainly want him to know that other people shouldn't be touching certain body parts of his etc.
I expect I am over-analysing all of this. But would be grateful for your thoughts / experiences.
