...specifically in the context of discussing this with your children, I don't need to know your bedroom secrets (not unless you want to share!)
We have 2 ds - 5 and 4 - and have basically stuck with "willy" for want of a better word as this tends to be most commonly used amongst their friends - but what about girls? I loathe anything twee or silly and so far have just said private parts (yes I know that is a bit twee too) and they know the proper name is vagina. We have lots of questions at the mo due to another baby on the way and specifically "where will the baby come out of mummy"?
Not a big deal in the scheme of things, but would be v. interested to see what others do ...
