My DM was a SAHM until I was 11 (1990s) and then worked term time in a part time, low paid role until she retired in her late 50s. I didn’t go to paid childcare etc (1980s) before I went to school.
I’ll be honest- I liked it. I liked the security, coming home to a warm, lit house where on cold days she’d have soup or something ready. She was engaged, checked homework diaries, asked about our day, and if there was something amiss she could always tell- we were her focus. She was always there in school holidays too.
I work 4 days a week and have a DS at nursery, but it plays on my mind as I’d like to ideally be there in the evenings/late afternoons after school for him too; I don’t like my job but also don’t want to quit work. You lose hundreds of thousands over your lifetime if you quit work, and I know that my DM was devastated when I left home for Uni at 18. Perhaps if she’d had a more engaging career of her own she wouldn’t have been quite so invested in me and upset by me leaving - but that’s not necessarily the case.
I should say, my DM was very ill when I was born and was unwell for years afterwards, we also lived semi-rurally. So, she was fairly unable to get a FT job even if she’d wanted one, and she also couldn’t get something P/T and well paid because she had no qualifications (grammar school but made to leave at 16 by a w/c Mum) and we lived in the countryside. A medical condition meant she wasn’t allowed to drive so couldn’t commute to a better job. We definitely missed out financially by her not working, and when DF lost his job twice in the 90s/00s we’d have been up shit creek if it hadn’t been for my DGran bailing my DPs out.
All of which is a long winded way of saying I have a 50:50 view of SAHMs. It can be great for the kids, but bad for the Mum long term. And actually if it makes your family quite poor, it can be bad for the kids at the time too.
It’s hard to be motivated when you don’t like your job (I don’t like mine) but I actually think for women who want more time with children then going part time gives the best of all worlds, if you can afford it. It’s really not a good idea to leave the labour market.
