Your baby's hearing is quite acute. Start with rhythmic and rhyming books, advises Egan.
Your baby's vision is still developing. Choose books with fairly uncluttered pictures, with good contrast and a nice mix of faces. Books with photos, particularly of babies, are especially good choices.
Engage in dialogue with your baby. When he makes sounds, respond to him. Call and response is important for his developing language skills.
Choose books with high contrast of colors and shapes.
