Your baby now actively engages in hiding games. Place a favorite toy on the floor and cover it with a napkin. Pull the napkin off and say, "There it is!" Cover it again and repeat.

For more fun, hide an object under something and wait for your baby to discover it. It's one of the easiest ways to keep him or her occupied!

Your baby can remember that the jack-in-the-box pops up at the end of the song – yet still laughs every time. He or she is also able to recognize different tones and inflections and may burst into tears if you speak harshly.

Because your baby likes predictability, he or she enjoys playing the same game or reading the same book over and over. In addition to patty-cake, try adding classics such as "If You're Happy and You Know It" and "This Little Piggy" to your repertoire.
