Infants who are developing normally should be
able to smile and coo when smiled at or talked to by 8 wk of age. By 3 mo
of age, infants should be able to follow a moving toy not only from side to
side but also in the vertical plane. When placed on his or her abdomen, a
normal 3-mo-old infant can raise his or her face 45 degrees to 90 degrees
from the horizontal. Not until 6 to 8 mo of age should an infant be able to
maintain a seated position.
