What your child is developing, and what you can do together.

For ages 0 to 18. Child development is the main thread, with free tools and activities to do together, plus health and safety essentials. We write no opinions of our own: every sentence links to its original source.

Why you can trust us

Every sentence has a source

We write no opinions of our own. Development points, activities and health essentials come from bodies like the CDC, WHO, the AAP and the Harvard Center on the Developing Child, or from peer-reviewed research, linked at the end of each sentence.

Evidence labelled, research checked monthly

Each entry says whether it is an official guideline, a large study or review, a small study, or expert opinion. Every month we look for new reviews and large studies and add them after checking; anything that overturns a conclusion is updated first.

Fewer, better picks

Each stage keeps only what matters most, and shows when it was last updated. No submissions, no ads, no sponsors.

We collect no data

No accounts and no tracking. Your child's age is stored only in your browser.

Free learning tools have their own pageKhan Academy, Code.org, Scratch and others, kept apart from the reading list. See free tools
