Sam loves pushing big things around (he's constantly redecorating and moving chairs everywhere we go), while Anna loves going for a ride: A win-win situation!... that is, until we have to go inside, and then mama's the one that loses (double the toddlers, double the tantrums).
Check out Anna's driving postion in the first video- one hand on the stearing wheel, one arm resting on the window. I wonder too, if she thinks she's steering the wagon while Sam's pushing her around in the second video!
