Can't believe I've just read this entire thread. Hilarious!
I work in a child care centre, looking after the children of other working mums. If it were not for them, I would have no job, therefore not be able to pay the bills. Thanks working mums!
My daughter comes with me, but is in a different room. (She's in the toddler room, I currently look after the 3-5 year olds)
Not sure where I fit in this dichotomy that you've created OP.
As long as your kids know that their parent(s) love(s) them, it makes no difference whether you work casual, part time, full time, 1 job, 9 jobs, from home, away, for necessity, for money, for career, for fun, or stay at home.
OP, get on with your life. Let others get on with theirs and be grateful for the priveleged position you are in to even have a choice.
