One of my favorite things to use in crafts is food!! Not only can kids be creative, but they can taste their art too. It's fun and messy and delicious!
I first had D paint with pudding when he was 11 months old...I don't know why he used actual paint before I gave him pudding paint...but oh well.
In this picture he was using butterscotch pudding, but other times I gave him vanilla pudding, separated, and put in a few drops of food coloring to make different colors. The best paper to use for pudding painting is the white glossy stuff, because otherwise the pudding leaks through the page, but if all you have is plain ol' paper don't let that stop you!! :)
Other "edible" paints you can use is sweetened condensed milk, applesauce, or jello (just add half the water...it gets goopy and sticky)
