Create a photo album of all the important people in your infant's life. Enlarge each picture. Go through the book and say each person's name. The photos could also be posted on a bulletin board with names written under the photos.
Your infant learns language concepts through play. While your infant is on a soft blanket, hold your infant's hands. Gently bring your infant's hands down to the sides of the body. Gently bring them up to a wide arc above your infant's head. Repeat as you sing, "Here we go up. Now we come down."
