"If I said I didn't see how anyone could be happy staying home letting their brains turn to mush I'd expect some protests."
Not being in paid employment doesn't mean you're not using your brain.
Since becoming a SAHM I've done a DIPHE (took me 5 years of part time study), done voluntary work, sat on committees, read lots and lots of novels. In or out of the work place, you have a choice - you can let your brain atrophy or you can carry on challenging yourself.
"The implication that you're not interested in your children if you work is pretty clear"
There's a difference between being interested in your children and being interested in spending time with them. I mentioned my SIL earlier on this thread. She's a teacher who keeps her 3 year old in full-time nursery during the school holidays so she can go shopping. She loves him just as much as I love my children, she just doesn't enjoy having to care for him on her own all day. Fair do's - there are plenty of men who only spend 15 minutes a day with their children who think of themselves as loving and involved parents.
I just think it's a bit stinky from nephew's point of view. Yes - he feels loved and is well cared for in every way, but he does spend most of his waking hours being cared for by nannies (who come and go) and 19 year old nursery nurses. Don't think that's what he'd choose for himself if he had a say in things. He'd rather be with his mum or dad.
