I got this idea from Play Create Explore.
I set up a big sheet of paper, paints, paintbrushes, and sponges, and let both boys paint. It’s fun now that Sweet Pea wants to get involved. He grabbed a paintbrush and put it right in the paint. And then flipped it around so the paint-covered part was in the palm of his hand. He ended up sitting on the paper and getting covered. But they both had a lot of fun.
