How much is too much

I've hit the classic working mom hump. My husband has decided that I'm not doing enough at home and too much at work. What is the right balance? How important is our housework compared to the time I spend with the children?

My priorities are my kids, my family and my job over housework. Apparently I have to drop some work items and place more importance on the housework.

I'll be honest. I don't know what I'm going to drop. But clearly I'm going to have to drop something.
