I’ve got this to come but with my 7 year old (and 4 year old) we just give honest answers. They ask how kids are made all the time. Then forget. Then ask again.
I never had any talk or what not.
I remember asking my dad what a prostitute was aged 10/11; “a lady of the night son” that kind of crap answer.
On the flipside my ultra conservative Christian brother in law believes a child should never see it’s parents naked and shouldn’t learn about sex ed until a teen.
That must awkward getting his little kids dressed after swimming etc.
