Influence of a family conflict on psychomotor development of a child in the first eighteen months after birth

As data show, psychomotor development in three-month-old babies from two groups (children from conflict families and children from normal families) does not differ, but by the age of 20 months children from conflict families lag behind their peers from normal families in sensory, cognitive and emotional development. Despite less obvious neurological symptoms at 3 months, neurological conditions in conflict family children lasted longer. The dependable type of attachment to the mother was also less common.
