Our jobs are headmistress and hospital consultant / medical lecturer. We don't eat with our children because it's nicer to play with them, school reading book etc from the time we get home until the time they go to bed that telling them that broccoli doesn't taste like shoes.
"I couldn't sit and play with the kids, make a mess then swan out and expect someone to clean up after me."
I can. I see it no different to expecting someone else to do the dishes after you eat in a restaurant.
After school activities: it can mean a later collection time but you're assuming that your multiple children's activities all coincide.
I love cooking as well as grocery shopping but not for children. The recipes I like have salt, cream, butter, wine etc.
It's rare that we don't put our children to bed before going out.
Telling children you can't do something is life but it's nice not to. If they want to go to the swimming pool it's much nicer to say yes rather than, I have to clean the guest room.
I understand that some of this is blurring the lines between house keeper and nanny but house keeping and other chores are much worse with children either because there's more work (laundry etc), because doing them with children is harder or because you'd rather do the fun bits and pay someone else to do the other bits.
I also understand the argument that bring children up with privilege could set them up for a tougher life in the future but it seems pointless to hold things back that could make your life nicer or easier to teach them a lesson. I couldn't do a Ramsey and stick them in cattle class with DH and I flying business.
And I hate to break your bubble but soft play is always horrific. You may not need to be involved when they're a little older but you're still in the noisy germ-fests. Besides which, there's usually several "Hello Mrs ClarkyMcClarkason"s from children or parents wanting to talk to me when I want to read my Kindle or whatever else.
As you rightly pointed out, the universe doesn't revolve around children and it's a poor lesson to teach children it should yet I also seem to have come in for some flack for not doing everything for my children. I don't quite understand the issue.
I'm not a "kiss Mummy goodnight now go to bed with nanny" parent but rather see it as the ultimate childcare when we're at work or when I feel I'd gain little by being with my children (soft play, for example) and much more having a nice child-free hour or two with DH).
