This morning Tressa is eating some cookies that we had on the top shelf of the pantry. I ask her how she got them, and she gives me this elaborate story of how she took the ladder off her bunk bed, carried it downstairs by herself, set it up in the pantry and climbed it to safely reach the cookies. She knew I didn't buy it for a second, and then confessed everything, and even reenacted it for me. I am reinforcing this behavior by making her pose for the camera???
