A lot of recipes for homemade play doughs claim to be edible, but actually contain a lot of salt. If your child is like my little guy, he eats more of the dough than what he plays with. So to avoid salt poisoning, I had to just not let him play with play doughs.
Then I found a very simple recipe for a play dough that only has two ingredients: flour and water.
2 cups flour
1 cup water
Mix the two ingredients well and knead like bread dough. You can add food coloring, if you like. This play dough has a much stretchier, elastic-like consistency than salt dough, but you don’t have to worry about your child eating a bunch of salt!
Store in the fridge when not in use. It should last several days.
When taking out of the fridge to use again, let it come back to room temperature to be soft enough to use.
