CHALK and PAINT are 2 things my daughter enjoys but put them together and WAHOOOO!!!
In a muffin tin mix water and cornstarch and then add some food coloring to make colors. Grab the paint brushes and head outside for creativity and play.
My daughter created several spots of artwork but the hubby and I also jumped in and had a great time with her. My 15 month old was sleeping during this time but I believe he would have enjoyed it too. We might have to do it again soon to let him create and explore with it too. :)
