We broke out the homemade play dough today. It was so much fun! With 1/2 a cup of salt, the stuff tastes nasty, so it doesn't get consumed by the toddler :)
In fact, near the end of the play time, she was pretending to eat the play dough, making chewing noises, and then offering it to the husband and I to try ourselves. Unfortunately, the last time she did that, she got tiny bit in her mouth as she was pretending. She tried so hard to keep a straight face as she held it out for us to eat it, and then lost it as she spit out the nasty. It was classic.
