ft mum is hardwork, you've less freedom unless you have someone to look after the baby for you occassionally, it's a 24hr job, at work you can finish at a certain time, but looking after a baby is lot more.
Of course money wise, I'm less free than when I had my own earnings, but I'm glad I'm at home to teach my son and watch my daughter take her first step, and mumble her first "ma ma"!
