Early hospitalization and disturbances of infant behavior and the mother-infant relationship.

The impact of brief early hospitalization was investigated in a controlled natural experiment of 14 children with cleft lip and palate (CLP) who were hospitalized for palatal repair at 9.5 months of age, and another 13 CLP children who were hospitalized at 12.5 months of age; 14 children without clefts who were not hospitalized served as controls. After hospitalization children were more likely to avoid their mothers both following a brief stressful separation at home and in the Strange Situation. It was suggested that CLP children may have learned to cope with stress by shifting the attention away from the mother.
