Pre kids, you can be think you're immune to the judgement and pressure to make your own choices.
And in the UK, we have a culture that supports, or at least equally judges, sahms and wohms.
Don't underestimate how hard sahm life is, with a culture where it's accepted as a choice. In the UK, you can be isolated and people forget you may have a profession, and be a real person. In Sweden, your job IS you. Without one, you're not a full person. There's no back up for sahms, no toddler groups, playgroups, singing time, etc, nothing. I think there are one or two expat groups in Stockholm, but in the country, there's nothing to do as a sahm!
I have been there, pushing a child on the swings, day after day, alone. No adult company during working hours. Listening to the sounds of the kids in Davis playing, being asked what I do, and what I earn, and not being a real person.
How fluent is your Swedish? If you're planning to be a sahm, and you'll sound like a toddler yourself for a while, it sounds like a nightmare.
