Example: When we read about trucks, or animals like bats I ask him: Do trucks fly? Does a bat a daytime animal? Can cat swim? Do butterflies have wings? Does mommy have wings? Do you have whiskers?
It's kind of funny what king of answer your baby can give you. It's just fun to do that. And we play that a lot, because Eaton initiates that game constantly.
I apply that game to these three printable worksheets I prepared for Eaton. (2 of them are on this picture)
