I take the view that you shouldn't judge other people and a "you do you" stance in life.
Personally, I have a two year old daughter who is the light of my life. With our current finances, there is no way I would be a SAHM as honestly, I would be bored out of my mind as I love a mental challenge. This doesn't mean I love her any less, it's just me acknowledging my own faults and knowing I wouldn't be the best, happiest mum I could be. Plus her childminder is basically a fun auntie to spend time with.
Now if I won a ridiculous amount on the lottery, I would like to think I would still work at least part time. If that wasn't feasible, then I would probably still enjoy being a SAHM more as I'll have the finances to go out and do anything I wanted to feel our time. I could even still keep her childminder for a couple of days a week and get 'me time'- which I don't get now as I'm either working or looking after my daughter.
Selfishly my happiest life would probably be part time work/lady who lunches me time and part time SAHM.
I admire SAHMs as I know it is a difficult job and I have the financial choice to not have to do it.
If my daughter grows up and she wants to be a SAHM, then as long as she is happy and fulfilled with that choice I will support her 100% of the way.
At the end of the day, as long as people are happy with their choices and acknowledge their faults, there should be no judgement.
