The early childhood provider, because of the consistent contact over time with infants, toddlers, and their families, is well positioned to observe the nuances of the early caregiving relationship; monitor early child behavior and development; identify deviances; and offer support, guidance, and intervention when families struggle. This partnership with families is further enhanced when the observations about child behavior, development, and psychosocial functioning, are communicated to the pediatric provider. The opportunity for this enhanced "developmental surveillance," incorporating additional observations of child behavior and development in multiple settings, provides valuable information to the pediatrician and adds to the comprehensiveness of the pediatric care provided.
