Like a tornado went through here

This morning I got up, made breakfast, emptied the dishwasher, filled it up, and cleaned the counters. I tidied the toys, cleared the coffee table, swept the house, and made banana bread. One of The Boy's friends from daycare -- his mom is on mat leave with her newest one, six months old now, and they were coming for a visit. 

A few hours later, after two two-almost-three-year-olds went through the place, it looks like a bomb went off. The kitchen is full of snack remnants, there are toys all over the floor and the coffee table and the kitchen. 

I do not know how the daycare people do it all day. Seriously. When two two year olds can make such a big mess, how do they cope with twelve??
