I watched the clock and tabulated the outrageous amount of multi-tasking that transpires in a simple minute. OK, here is what happened in our house from 5:01 to 5:02 pm.
Helped son 1 with peeing in the potty. Let dog out. Listened to cord of a Hilary Duff song with daughter 1. Got daughter 2 into Spider-man costume. Picked chewed up Starburst off the floor. Put popcorn into bowl for kids 1-3. Played patty cake with son 2. Let dog in. Gave dog water. Took Game Boy away from son 1. Negotiated a fight about the attributes of the Incredibles vs. Spider-man between son 1 and daughter 2. Gathered spilled popcorn off floor. Answered sales phone call. Untied knot in shoe of daughter 2. Helped son 2 up from floor. Wiped son 1's runny nose. Helped daughter 1 spell "Bettis." Helped daughter 2 spell "Dash." Checked email.
Times that by 12 hours plus a day and my lord people, how do we do it?
