One of the great milestones of this period is the social smile. "It indicates that the child's psychic and affective development is doing well," says the pediatrician. It is a curious phenomenon, because it is independent of the look and receptivity of parents. "Blind and deaf children also have that smile," says Rosa. In addition to the smile, the 2-month-old baby can already lift his chin, signaling that control of the neck muscles is advancing. It also has the reflex of turning the face sideways if facedown when awake. Other reflexes, such as extending the body backwards if suddenly raised and walking, begin to be inhibited because the mastery over the movements increases. Vision - the two retinas fuse together - allows the baby to fix and track objects and people. He sees his mother differently. Not just the outline of the face, as it was before. See details, the nose, the mouth, the lips. Can recognize father, grandparents, nanny. At this stage, it is important to continue the pediatrician-oriented vaccine calendar. It is that they also depend on the development of the baby. They have dates to give because the tissue that produces the baby's immunity, the lymphoid, has a certain rate of growth. "It is no use immunizing the baby first because his body will not be able to respond to the vaccine," says pediatrician Francisco Lembo Neto.
