Don't agree tbh, I have been both, working full time, single with four children, and a stay at home mum, and tbh, I found that after being at work, I came home feeling full of energy, energized from seeing the people I worked with (loved my job teaching at a school with kids with behavioural problems) and loving being home with the kids, and found it so much easier to sort dinner, get the house work done, get the kids sorted for bed and so on, however, when I was a stay at home mum, I found by the wednesday, I was bored shitless, most of the jobs already been done, and I found it hard to get into anything, and by the time the kids got home, I felt knackered!
I am a stay at home mum now but I also home educate my kids as we lost all confidence in our local schools, so I am working bloody hard, trying to give my kids a fun childhood, but still more exhausted than when I was working! ;-)
Basically, I agree with those who say don't judge! Who gives a shit, as long as you're happy doing what you're doing, and if not, change it! :-)
