I must admit I did used to wish I could have a spell in hospital (or something similar,) many years ago when my kids were little, because I used to do EVERYthing, and I was always the one called and expected to step up if one of the kids was ill at school or the childminders. And I worked too. AND looked after elderly parents..... DH rarely helped as he had a physical factory job, (and did shift work,) and was 'always tired....'
In addition, it was always expected that I should book leave from work, not DH, if the kids were off and the childminder was unavailable etc etc.
No-one ever expected DH to do it, and he always came up with the crock of bollocks that he can't get time off at short notice like I could. 
When our kids were infant age, life was really stressful, with little family help or support, and not much surplus income. We both worked, and there was never a reprieve. As much as we loved the kids, there was no break.
There never seemed to be any down time, or time to relax, or any money to do so, as we were always forking out for something; usually house repairs, or car repairs, or something the kids needed, etc.. And it was more stressful for me, because - as I said - I did pretty much everything; housework, childcare, the works...
Then when the kids were around 7-8 y.o, DH had a weird kind of severe pain in his heart, and started clutching his chest, crying out loudly........ He told me to call 999, and so I did. They took him into hospital where he stayed for 10 days, as he claimed he had a bad heart.
He had test after test and they found nothing wrong.
I spent almost 2 weeks run ragged, doing everything, (although I pretty much did anyway!) while he lounged around in hospital being waited on hand and foot. I swear down, to this day, that there was nothing wrong with him, and he was laying it on to get a rest in hospital......... In addition, he was written off sick for a MONTH after that, and did FUCK-ALL for that whole month except get under my feet and dominate the tv!
Now, 15 years later, we are 50, and I took early retirement from my civil service job last year, after 33 years, and have a decent income from it. DH has hopped from job to job (5-10 years in each,) and doesn't have the luxury of early retirement. He is actually royally fucked off and incensed that he cannot retire til 60 at the earliest. He doesn't resent ME having finished work, he is just annoyed that he can't finish as well.
Well after 33 years of work, looking after elderly parents (they passed a few years ago now,) and looking after kids, and pretty much doing 95% of the childcare and everything in the home, and rarely getting a lie in; I now have a life of reading, writing stories, surfing the net, watching netflix, lying in til 10am, going for long walks and bike rides, having coffee and lunch with friends - or one of the kids - going horseriding, going to the cinema, going out taking photographs, crafting, tending to the garden, and doing whatever the fuck I want.
I deserve it too, after being everyone's handmaid for so many years. DH has to keep working another 10 years at least. And the kids are just starting their work lives and careers. It's now my time to relax and enjoy life, and my GOD I am enjoying it.
All good things to those who wait.
