Gosh, that Withers piece is interesting. All those questions and no answers.
Whatever are the parents of this boy thinking? Unless the mum genuinely thinks she's the Virgin Mary, then she must have some idea about how babies are made. Surely mum and dad realise, however "kind" everyone is, that puberty will show itself at some point? And, never mind the girls around, that's not going to be at all nice for their little boy? How do they sleep at night, how do they justify this on their son?
I don't understand how parents can do this to their children. The only parent I know in this situation appears to be completely delusional, but even she subtly dropped her son out of Scouts to avoid questions about camping etc. So she knows really. But these parents are next level.
