Developmental Milestones Checklists for Infants and Young Children [downloadable]
Developmental milestones are behaviors and skills that most children demonstrate at a given age. It’s important to note that all children develop differently. Milestone checklists provide examples of typical development progress at that age.
In February 2022, the Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) revised the developmental milestones. An individual children may develop more rapidly in some areas than in others, and the time frame in which a normally developing child reaches a certain milestone can vary quite a bit. The new milestones identify behaviors that 75% or more children can be expected to exhibit at a certain age.
