Have two canvas's on newspaper. Put painters tape in random places and spots on the canvas and let the baby or anyone, do the painting with paint sponges! When it dries, take the tape off and have a look at your masterpiece!
Make one for each child and then add hanging folders that say "Pre-K through 12th grade" save things that come home during each school year (report cards, drawings, certificates, good grades, etc.) Love this idea
