Ask your child to think about all the food that went into their tummy today. Was anything not just good, not ok, but delicious? Then ask your preschooler about familiar foods. Is that crisp, red apple tasty? Maybe those raisins in your cereal were delectable. Making comparisons using their sense of taste sharpens your preschooler's cognitive skills of contrast and comparison. And remember, reflecting on things is always good mental exercise for your little one.
