I work full time, and it's very hard. DH & I do tag team. He gets home before me, so he gets dinner started, then when I get home at 6 with the girls, I take over from dinner and he takes the girls outside to play. We usually eat around 6.30. We meal plan, so both dh & I always know what is for dinner that night.
Each night, we do a little bit of housework. Floors, or washing, or something. That way by the weekend we don't have to do too much.
