Talk or sing to your baby when you change his diaper, give him a bath, feed him lunch or join him in play. Introduce cardboard or cloth books with brightly colored pictures. Be aware that at this point, your baby might enjoy looking at, tossing, or chewing the books more than being read to! Help increase your baby's vocabulary by playing "What's that?" or "Where's the teddy bear?" when enjoying books together. Point out words on signs at the park, at the zoo, or when walking or driving. As children begin to notice letters on blocks or other toys, name the letters for them. Read words aloud and explain what they mean.
