Your baby will begin to understand simple words. She stops to look at you if you say “no-no.” If someone asks, “Where’s Mommy?” she will look for you. She will point, make sounds, and use her body to “tell” you what she wants. For example, she may look up at you and lift her arms up to show you she "wants up." She may hand you a toy to let you know she wants to play.
You can help your baby "talk" when you show him how to wave "bye-bye."
