As you are driving in your vehicle, ask your child to identify various items. For instance, ask her to find a bus, truck, flag, barn, McDonald's, etc. Once you approach the item, point it out and say, "I see the yellow bus." At first, focus on things that your child will easily recognize, then add a bit of a challenge. This game can also be played in a restaurant while waiting for a table or your food or anywhere else a toddler might have to wait. As your child gets better at this game, she might be able to ask you to find something.
Show enthusiasm and change your vocal tones as you say different things.
