Frequently asked questions

Does this replace my pediatrician?

No -- it's designed to help you organize your own observations and know when something is worth a call, not to diagnose anything yourself.

Is this only about physical symptoms?

No -- it covers developmental milestones by age, mood and behavior patterns, and physical symptoms, all organized so you can find what applies to your concern quickly.
