Paint? On the windows? Why, of course! Breaking the “rules” is so much fun. For this activity, lay out a drop cloth in front of the window, storm door, or sliding door of your choice, then use painter’s tape to protect the frame. Bring out some brushes and for your kiddo to use on the glass, and voila! This is a great way to use rainy weather as a wonderful canvas. When you’re ready to part with your child’s masterpiece, simply wash it off with dish soap and a wet sponge.
