So far we have only had "the" conversation with our 8 yr old but our 4 yr old asks some questions. We call thing by their right name here.. Vagina and penis. although the boys say willy, nuts goolies ect

We Told Ethan (8) a certain amount of things using a book from the library. things i didn't tell him were how the sperm gets inside the woman to make the baby. in other words the actual act of sex. he has an idea but we said we didn't think he needed to know that bit of information just yet...

and that satisfied him nicely. Just be upfront and honest and use normal adult talk rather then dumbing it down kwim???
