"Frequent longitudinal contact with young children and their families at critical times in their early development provides pediatricians and other practitioners with important opportunities to conduct developmental surveillance and screening to detect clinically significant developmental problems and institute early intervention. Early identification and referral to early intervention programs can ameliorate the negative consequences of developmental problems on children, families, and society" (Drotar, Stancin, Dworkin, Sices, Wood, 2008).
