Kids’ milestone s-curve visualizer: ages 0-5
I’m occasionally frustrated that my kids' developmental milestone achievements are reported purely as boolean: "By 9 months, he should be doing X." But obviously there is a distribution of when kids hit those milestones! It's just not easy to find what it looks like!
I found two datasets from large US studies that include actual parameter data for a variety of milestones.
So I categorized the achievements and used those parameters to visualize them on a filterable, scrollable timeline.

(Note that these are different than CDC milestones, and CDC uses different/more data to come up with their recommendations. Don't panic!)
**Data Sources:**
* Sheldrick, R. C., & Perrin, E. C. (2013). *Evidence-Based Milestones for Surveillance of Cognitive, Language, and Motor Development.* Based on a sample of 1,172 families.
* Frankenburg et al. (1990). *Denver II Technical Manual* for specific motor markers (Standing alone, etc.)
**Tools:**
* Item Characteristic Curve (ICC) parameters from the paper to produce the s-curves
* Recharts for plotting
