"Friends of ours do 50/50 so their two kids go to one sun - wed then to the other wed- sun then alternate the week after. Initially I thought the kids were being passed from pillar to post but it works for them and now I think it sounds like a good idea. My dh would almost def want this.
I wonder why most courts don't favour this?"
a. as a poster has said earlier, often it doesn't go to court; parents decide informally, and the set-up you find so odd (female parent having residency of children) is what both parents have decided.
b. the courts decide in favour of what is deemed to be the children's best interests.
So the question then becomes: "Why do most parents opt for this set-up?" and "Why is it so often deemed in the children's best interest for teh mother to be the resident parent?"
The answer almost certainly has a lot to do with the continuation of gendered domestic set-ups.
I will admit that I think your OP is amazingly naive not to have thought this through. Do you not know any single parents? Have you no imagination? And what I mean by that is this: you say "Oh my darling husband would be heartbroken by losing contact with the children" but presumably you are not considering separating from him? Try and imagine the sort of behaviour that might cause you to feel alienation from him? For example, acting in a way that is massively disrespectful, hurtful, or just plain harmful for the children? It may surprise you to know that some NRP do this. And that is how they end up as NRP. Extrapolating from you husband to the NRPs who don't have full-time care of the children is utterly pointless.
As an example, I know one NRP who made child pornography with his children. That's how he ended up as an NRP. He was also an abusive bastard to his wife. So. There you go. One answer. As you can probably see, extrapolating from your husband to Mr Chappie here is thick, frankly.
An awful lot of other NRPs just sodded off.
Yes, yes, there are some chaps out there who are utterly devastated and heartbroken by not being the resident parent, and are prevented from seeing their offspring by evil, wicked women. But I do think they are a very small number.
I look around the people I know and, to be honest, the flakey dads were just flaky - when they were married/in relationships, and when they weren't; the dads who wanted to be parents carried on being parents even after a split; the shit, irrepsonsible ones, who fucked off/were binned for being crap, carried on being irresponsible/shit; the ones who were downright dangerous carried on being that.
