This may be really stupid but...
I've always taught DD that boys have a penis and we sometimes call it a willy, girls have a vagina and we sometimes call it a tiddy, breasts we call boobs etc. We're getting deeper into it at the moment because I'm pg and she wants to know more about how it happens and bodies etc and I'm happy to tell her but just been reading through a book on the subject I've got her for us to go through together and it goes into testicles and how they make sperm etc.
So long story short - is is OK for an 8 yr old girl to say balls, or nuts? I can't work out if it's vulgar or actually a very accurate and normal word for them. When I was young they were goolies which I think is fine but is it a bit silly or unnecessary? What the concensus here, what do your kids call them??
TIA!
