Teach your toddler the where sign in conjunction with prepositions, to expand their vocabulary on the location of things, people, and so on. "Where is your bear?" "Is it under your bed? Is it in the drawer?"
Use the where flash card when you begin to explore compound phrases. This sign is best for toddlers and very easy to teach through games like hide and seek, or by placing various objects and asking your baby, "Where is the pen? Where is the pencil?"
