The CradleNote team adapts activities from our Growth catalog and links the CDC, AAP, and Harvard sources that inform the guidance. We add practical setups and caregiver examples. The examples are illustrative, and the source organizations do not endorse CradleNote. You can enjoy an activity without photographing it or deciding that a milestone was achieved.
