Prepare a number of interesting foods for your baby to touch, taste, and smell —in very small amounts—such as fruit flavored gelatin, yogurt, banana, O-shaped cereal, oatmeal, spaghetti, and so on.
Spread a plastic floor covering in the kitchen, and place the highchair on the covering.
Seat your baby in the highchair and place one food item on the tray.
Let your baby play with the food for a few minutes, exploring it with her hands and mouth.
Remove the food and offer a second item for exploration.
Watch your baby's expression as she examines each new food. Make sure to name and describe each item as you place it in front of your baby.
