I used to work full time, in a managerial position with a large team under me.
It was piss easy compared to my life now.
I've just had my 10th baby and am now a sahm.
I am responsible for all my children's safety, doctors appointments, assemblies, other school events, 5 of my children are ASD and require regular appointments for that plus my ASD toddler has several SEN toddler groups we attend because we don't qualify for free nursery hours yet and it's the only way we can get him the stimulation he needs until then.
I get zero help from grandparents (the same people who I seem to remember being more than happy to get help with us when we were kids but now have a "I've done my childrearing" attitude when it's come to their turn), I don't live anywhere near any friends as our delightful landlord issued us with a section 21 last year and we had to relocate.
I'm going on three hours sleep today, I'm constantly unwell, I sometimes forget to even eat until the evening because I'm so busy, no handy lunch breaks for me.
But yes. My life is a walk in the park because I don't have to arrange childcare for school hours.
I sit on my arse all day and overplay how hard things can be.
I realise I have a much larger family than average, but a lot of what I face in a day is not specific to a large family. It's standard day to day business for a stay at home parent.
Maybe read less of the Daily Mail and you'll realise just how ridiculous you're being, OP.
