With each passing week, your newborn becomes more comfortable with his surroundings. But his vision is still blurred. In fact, a newborn's range of vision is only about 30cm or 12 inches, which helps explain why your face is the most interesting thing to him right now. While the rest of the world is a blur, he can clearly see who's holding him. So try keeping your face close to your baby's while you talk or sing to him.
