My mum was a SAHM, she had our days filled with fun, educational things for us to do, she ran the days like a bloomin nursery, it was great.
She was there to drop us off, pick us up, all our holidays it was lovely.
I wanted that for my kids, i had a great childhood with our mum.
Of course you can plan to be a SAHM, you marry someone with the same values as you and try to get yourself in the position for it be possible, obviously its not straight forward or even possible for everyone and some dont want to which is also fine.
Respecting others choices is key, and respecting the fact we have that choice. Not be offended by others reasons for their choices, its not a dig at your choices, just reasons for theirs.
My mum drilled into us a good work ethic, my nan worked off and on and always taught us to have our bus fare home (money to just leave and get rent money saved), my MIL worked, and my FILs mum worked, so surrounded by strong women who chose to take time out with their kids and then back to work when kids are older. Great strong women who made great choices, for them.
