Purpose:
Evaluate the content and variability of infant motor milestone education provided to parents in popular sources.
Methods:
Sources were screened for inclusion, and their motor milestone content was coded. Descriptive and inferential analyses were performed.
Results:
Content from 241 websites, applications, and books was evaluated; 6984 motor milestones were extracted, representing 146 unique milestone codes across 14 categories. Books and applications had more milestone content than websites. There was variability in the milestones mentioned and their associated ages across the sources and relative to the American Academy of Pediatrics (AAP) and Centers for Disease Control and Prevention (CDC) content. Several frequently mentioned milestones were behaviors that facilitate early learning.
Conclusions:
There is variability among sources in the motor milestones they provide to parents of infants. The AAP and CDC content likely has some influence on the broader content available, but there is substantial deviation from the information they provide.
