I just found a super cool one on Pinterest that I'm gonna try with my son tomorrow. Basically, you reinforce the sides of a gallon ziploc bag with duct tape, put a big blob of finger paint in the bottom corners of the bag, fill the rest with white foam shaving cream, then seal the top with more duct tape. Then kiddo can mash the paint around and turn the shaving cream colors. The duct tape is just to make sure none leaks. I'm super excited to try it with my son.

My sister (14 mo) loves making messes. I've seen people buy a big painting canvas with different paint colors so they make their own paintings. We have a small pool and sandbox, too. Maybe try finger painting or something artistic or sporty. What type of things does she seem to enjoy most?

Pinterest ! And YouTube might give you some ideas .
