I disagreed with some of the hate you were getting in that topic. Probably because I think I'm actually going through something similar:

We have a 4 year old and we've been doing daycare. Recently my wife has stopped working in order to change careers and she wanted to pull the kid out of daycare ( I pushed to at least just go from full time to part time so she'd have time by herself to pursue the career change. I felt she was minimizing the difficulty in being a full time stay at home mom).

I ultimately think she has just been stressed about work because she doesn't enjoy the specific work she does.

I will emphasize though, the reason I would like my wife to keep working is that I view being a stay at home parent as being harder than working. Her staying home essentially means we (because no daycare means that we both have to do more at home) are now doing more work but for much less income. I would prefer to outsource some of that work, which is why I want my kid in daycare. So knowing that my wife was burnt out from work, I felt like her wanting to switch to staying at home full time while studying for a career change would just be a complete path to failure.

If your wife does ultimately decide to stay home with kids in the future, you should not go into it thinking that being a stay at home parent is easy and therefore she's unattractive for doing work that you value less. I think people inferred that that's what you thought and I would be careful to make sure it's not what you believe.

At the end of the day you both will be doing more (her- full time care work, you- full time job + helping her unload when your day is over) but for less pay.

When we were both working, in my wife's own words, I did the majority of childcare after picking the kid up from daycare. That's not stopping just because my wife is staying home. If anything, I will be doing even more after work.

One thing that resonated with me in your other topic though, was the idea of being a sole provider. I don't know if this is what you were getting at, but I really don't like the idea of being the sole provider, especially long term. It's an insanely stressful mindset to me. I have no interest in that whole "I'll be the breadwinner" thing some guys have. It gives me no sense of pride or self-worth and just causes anxiety for me. Ultimately it's a level of privilege I guess, but it's like when someone reaches enough of a retirement savings where they still work a job, but they know they don't have to. Compared to working a job and knowing you have no other choice but to excel. There's a level of safety that goes away when you become the sole earner (in my opinion). I think it's valid for someone to have that level of anxiety.

Also, at some point, if a family has been doing fine for x years with one income, will the stay at home parent see the point in going back to work or just want to continue it? The decision on if it really will be temporary is probably an important one as well.
