Some people are dicks to other people.
I have been a sahm but worked for most of the time I have been a parent. If someone wants to be a sahm and they can, thats great. Entirely their own choice.
However, getting a job is often the answer to many sahms issues. The IVF one, op used the words '100k salary isn't alot to raise a family on'. Apparently, the dh hadn't been earning that long. But she still didn't think it was much.
If a sahm wants more money coming into the household, then they need to look at ways they can achieve that.
She was also to get a job, because ots clear her husband doesn't actually, see it as joint money and she needs to protect herself and her own future. If that's the case.
Yes, there were a couple of dicks. Just like there's dicks on the threads where mothers want to stay wfh, because it gives a better work life balance. Its usually, sahms that have the main problem with that. There's several sahms, who go from wfh thread to wfh thread making up ridiculous reasons why people can't work from home. Non of which are actually true. Doesn't mean MN hates working mums. Doesn't even mean that most mners hate working mums.
It means some people are dicks.
I am not jealous of sahms or part time working parents. I have worked flexibly for years and earn an amazing wage. I get the best of both and am financially independent. If someone wants to be a sahm, that's fine. I prefer my situation, though.
But often not being a sahm is the solution to their problem.
Like if i posted that I never get to see my kids, people would suggest reducing my hours, or looking g to see if I could take a career break and be at home etc. Would that be hating on wohm?
I do also think that women need to think very carefully if they really are just giving up work, to save childcare fees. That few years, can damage their earning potential. Staying in work is often a long term strategy.
But it really is their choice.
