Less than a quarter of children with developmental disabilities receive early intervention services before age 3. The recent update to the “Learn the Signs: Act Early” guidelines is a step toward more children and families getting help sooner. Kate Wallis, MD, MPH, a developmental behavioral pediatrician at Children’s Hospital of Philadelphia, reviews: how and why the changes were made; how evaluating milestones when 75% of the age group is meeting them (rather than the previous rate of 50%) affects the wait-and-see approach; why it was important to add milestones for the 15- and 30-month visits; how the milestones may be helpful to parents; and more.
