I covered the floor and put Baby A in her jumper. I then painted her feet red with washable finger paint and let her stomp her feet on the paper. I switched out the paper a few times so we'd have a bunch in the end. I let the paper dry a little bit, and then repeated, painting her feet yellow and green.
After the papers were all the way dry, I cut tree trunks out of brown construction paper, and glued them on the page where they looked right.
Beautiful Fall Trees, by Baby A!
Once everything was done, we sent them off to the grandmas and grandpas, and covered the fridge too!
