Some people think going to work is easier than being at home looking after children.
Some people think going to work is easier than being at home in an empty house for most of the day.
Some people work/sah because they don't have a choice and have to get one with it.
Vice versa.
There's so many factors like disposable income, having a dh who pulls their weight etc as to if someone will find whatever easier. I know it sounds cheesy but if everyone does what's best and what works for their family then everyone is an equally great Mum.
I hate the way society judges women for making choices different to theirs, either criticising them and/or being jealous because their own circumstances mean they can't have same choice, and it's often women doing it.
I've had a gander at some male forums and I'm yet to find a thread where they are worrying about being called crap dads because they work 12 hours a day, or having a pop at each other and saying the Dads who work time or not at home can't find things hard because they don't work, or saying to each other why did you have kids if you're gonna plonk them in daycare, asking each other for tips on how to cook healthy meals after a long day at work.
It only seems to be women who have to worry about this stuff, and who are judged and criticised for it.
