My preschooler always has to know what comes next:
What will we do after preschool?
What will we read after this book?
He always has to be prepared for what's coming, especially when it comes to food. He will literally have food that he's trying to shovel into his mouth and he will say, "What else can I eat?"
My response to that lately has been, "Finish what you've got and then we'll talk about what else you can eat."
So now at bedtime, he asks, "What else can I eat? I mean, for breakfast tomorrow."
