My family is out of balance on many views. I have 3 daughters and 1 son. True balance would be 2 of each.
But others would look at me and say I'm lucky I have one son and 4 girls would be truly out of balance.
So if you have 2 of one sex and want a 3rd is it ok to say I want the other sex so therefore should be able to choose? Isn't that being out of balance because the single sex child will effectively be the only one?
My son sometimes says he hates being the only boy, but at the same time he has this fantastic life surrounded by strong girls and also can an incredibly close bond with my DH as they are the sole males.
The difficulty with saying families are out of balance is by whose definition?
I can't see how they could restrict its use that way. It's too hard. So yes you could theoretically design your own family.
