These threads are done to death. But here goes with my views.
SAHM of SCHOOL age neurotypical children who also have no disabilities/extra needs who is in reasonably good health, with a partner who is generally supportive- almost certainly easier than a mum working outside the home.
SAHM of children not at school, especially if toddlers/young babies and more than one child-arguably harder than working outside the home, but COULD be ‘easier’ depending on how many/any additional needs/how much partner contributes etc.
SAHM of children with additional needs who require lots of support- pretty much guaranteed to harder than a mum working outside the home who has children with NO additional needs.
Working mum of children with additional needs who is constantly being pulled in a million directions and always stressed about losing her job- almost certainly way harder than a SAHM of children with no additional needs.
Context, circumstances, finances, family support, what your working outside the job is like, commute, partner (or not and what kind) whether you want to be at home, etc etc the list goes on. It’s not a competition or race to the bottom.
I wanted to go back to work earlier this year. Wanted to, could not because of the needs of two of my children making it absolutely impossible. I am technically a SAHM. And actually, I love parts of being a SAHM. But having that choice taken away is also non ideal. Luckily I am okay about it, but believe me, even though 2 out of 3 of my kids are school age, I am beyond stressed a lot of the time. I am also aware of the fact I’m lucky to be at home in some ways, and that I get a break when my toddler naps etc,
