I would also advise to work small. We are busy raising children and can't make time for ourselves a large priority in life at this time. Yet making a commitment to yourself to give yourself the time and energy can create the small bricks that build pieces of your future. My husband has graciously provided for my own free time. She tends to the children until 6 when my husband comes home.
Dinner is either in the crockpot or on time-bake in the oven.
If I'm out late, Bruce feeds the children, interacts with them, puts them to bed, and cleans up. Sometimes I'll take one of our four young ones along so we can have time for just the two of us.
