*RainbowsAndUnicorn: I disagree, unless the child is SN so needs more care than the average child then being home is a doddle compared with working regardless of the job."
Well, I am going to disagree based on my own experience. I've done both being the SAHP (maternity leave, holidays, WFH, etc.) and I've done going into the office. No contest. My three year old is much harder work than my job. Other people's mileage may vary but you can't make a blanket statement that "being a SAHP is always easier than working (SN excepted)" because I'm telling you quite matter-of-factly that in my case, no. It isn't.
Their are no deadlines, no pressures, no boss, no change of being fired etc. With no job, you can stay home all day doing nothing is so desired.
You can't do nothing. The toddler still needs getting up, dressing, supervising, entertaining, feeding, taking out and about whilst you do chores, soothing through tantrums, "discussing" arguing to the ends of the earth with, etc. etc. etc. That's not nothing. Not unless you're doing it extremely badly.
Being a parent, whether or not you work as well, isn't a job. It's a choice we make when we decide to have children. Children shouldn't be seen as a chore or by number of hours supervision needed.
I live on planet earth where I both LOVE being a parent, and sometimes, want to scream into the sofa cushions because my DS has split a carton of cranberry juice by dropping it on the carpet by accident. Those incidents? The laundry? The tidying? The getting-past-this-tantrum? Those are chores. This is right out of the playbook of "you must enjoy every minute." No. I can be frustrated and tired and fed up and dispirited and even, some days, wonder wtf I was thinking having kids.
Working parents are still parents 24/7,
Yes, but I can't do any of the actual, physical parenting whilst I'm literally not in the house...
they come home around work and then do everything a SAHP does on top.
No. Some do. OP's entire point is that hers does not.
Strange how non working parents are still parenting whilst their child is at school but those working are not .."
Does the laundry/tidying/admin/shopping/appointments/prepping dinner/etc. all stop when the DCs go to school? Do the SAHPs sit on the couch doing nothing whatsoever every single school day? I'm sure some do, but I'm equally sure that plenty actually spend their days doing all this stuff and plenty besides.
