For adults. General information, not a screening, diagnosis, or medical advice. In an emergency, call 911; in a crisis, call or text 988.

How this works

Answers are written by Claude, an AI model from Anthropic, using a curated library of developmental research and From Little Onward class material. To write each answer, your question and the recent part of this conversation are sent to our server and on to Anthropic. We don't save your conversation: it stays in this browser tab and clears when you start over or leave the page. Please leave out names and other details that could identify your child. It can’t assess a specific child: if you’re worried about your child’s development, talk to your pediatrician or contact your state’s early intervention program.

Free gives you 5 questions a day.
