So much laundry!!

Why do I have ten times more laundry then I did BEFORE Alex was born? The kid only wears 2 outfits a day (the one he goes out in, and pajamas at night)...not to mention that they are extremely small clothes. BUT I am doing laundry twice, sometimes 3 times a week with 2 loads each time!! Before he was born, I only had to do laundry once a week! I just don't understand....it's not like Tom & I are wearing ten outfits a day!! lol
