This, genuinely, is one of the most interesting threads I've read in ages... Possibly because it's a topic close to my heart of late, but alos because of the range of choices and opinions expressed...
And yes, your background makes a huge difference to your priorities...
We were totally, unbelievably skint when I was growing up ? my Dad was 60 when I was born, retired when I was 4. My mum had given up her job as a teacher when I was born to be a SAHM, and didn't return when my dad retired ? I'm not sure why, I think she felt it was her duty to be there, even though Dad could cope better than she could just fine. She did part-time jobs, which paid badly, and as I got older I could never understand why she didn't go back to the classroom, where she could have earned more and used her skills, especially when I was in secondary school and out of the house at 6.45am and not back until 5.30pm. But her choices meant we lived on Dad's state pension and whatever Mum earned from bits and bobs (and before you ask, yes, I did go to private school from 11, but on a full scholarship so everything, including uniform, transport, music lessons the works, was paid for...), which was, basically, bugger-all. Lack of money was a constant source of stress and anxiety for them and for me, and I always felt a degree of guilt about it from really quite a young age.
So, for me, financial security is a huge priority, I don't want my girls to be worrying about money as children, or seeing their parents fretting about it all the time, or feel guilty about even expense that they cause, when there is an alternative. But also I want them to see that Mummy has a job she loves and not to feel responsible for her giving it up, as I did... But I also want them to know that I am available for them, if and when they need me. My new studio is five minutes from my house and ten minutes from school...
But, OP, not sure if you've run for the hills as it's all getting a bit contentious...
I think if there was a take out from this, it's that there are a hundred and one ways to cut the career/children pie, and, although some posters have strident views, I think it's clear that there's no one size-fits-all-solution...
Your LO is very young, still, you have time to think this through ? you can go back to work, and, if you hate it, or the compromises you have to make to do so, you can re-think/try a different path.
Of course, once you have 2+ DCs under 3, you may be desperate to get out of the house and into work... The most demanding boss in the world is nothing compared to the irrationality and unreasonable demands of a couple of 'terrible twos'...
Sometimes, (and today is SO one of those days,) my studio is a haven of peace and tranquility, where I can drink an entire hot beverage before it's stone cold, and hardly ever have to break up any fights...
