If a 3-year-old came to you and said, "I wanted my marshmallows cooked", would you panic? Now, if he came and said, "I want to cook my marshmallows" I wouldn't be too worried. But the past tense thing definitely causes alarm.
Yesterday I made a snack mix for the kids with popcorn, Chex cereal, chocolate chips, and mini marshmallows. Yummy stuff! But they ate it all! So Caleb decided to make some more, without any adult assistance!
He put some Cheerios in a bowl, put the rest of the mini marshmallows in, then put in the remaining Ritz crackers, and put the bowl in the microwave. Fortunately for all involved (especially the microwave) he only pushed the quick start button that only runs for 30 seconds - especially fortunate because he had his concoction in an aluminum bowl! I stopped it with 11 seconds left.
By the way, he did share this creation with at least two of his brothers.
