My mom was a stay at home mom for most of my childhood. She put her job as a physical therapist on hold until I was in junior high, and stayed home with me and my two younger brothers. To be honest, I don't know how she did it. I work 4 and a half days a week, and stay at home 2 and a half days. I only have one child, she had 3. I'm exhausted at the end of my home days. I can't keep up with him! Thank goodness for the 1-3 hours he naps - that's my chance to actually get some things done around the house.
Not that I actually like to do housework. Along with the "stay at home mom" gene, I seem to be missing the "must keep the house clean" gene. My mom cleaned house every Saturday, and straightened up every day. I pick up toys at the end of the day, do laundry once a week, wash dishes twice a day, and only actually clean the house when one of our mothers is coming to visit. It's not that I don't know how to, I just don't like to. And since I work till noon most Saturdays, there just don't seem to be enough hours in the weekend to spend time with Sam and Tommy and clean the house.
Maybe in a few years when Tommy is old enough to help. Maybe then we'll keep the house clean. Then again, maybe not :)
