So, I do what we all do when we need ideas and suggestions, and I turned to Pinterest. I found a recipe for homemade sensory paint and gave it a go this weekend.
This is the one and only time he touched the "paint".
Yup, I made him touch it once and there was no continuing until we cleaned him up. It doesn't paint very well with a brush as it's pretty thick stuff. He had fun none-the-less and we'll definitely try it again sometime.
It's super simple to make:
2 C cold water
1/2 C corn starch
3 T sugar
Whisk over medium heat until it boils and starts to thicken. Separate and add food coloring.
*You'll want to use paint shortly after it has cooled*
If all else fails, he says it tastes good.
