The People Behind Our Activity Cards

We want you to be be confident in the quality that went into the selection and design of our activities.

Our research is based on data-driven developmental findings from the following accredited institutions and child-centric resources:

The American Academy of Pediatric Findings, CDC Infant Information, U.S. Department of Health and Human Services, National Institutes of Health, and experiences from real moms and dads.

We couldn't have done this alone. We're thankful for the many medical professionals that are part of our advisory team, and want to highlight a few of key contributors below.
