Noticing developmental milestones
Organize your observations and questions.
Empowering Children. Supporting Families. Building Brighter Futures.
Use milestones to organize observations.
CDC’s age-specific resources cover how children play, learn, speak, act and move. Use an age-appropriate checklist to prepare for a conversation with a healthcare professional.
Bring questions, not a self-diagnosis.
A milestone checklist is not a diagnosis or a replacement for standardized developmental screening. Share concerns with your child’s healthcare professional and ask about appropriate next steps.
A simple preparation list
- Choose the resource for your child’s current age.
- Note everyday examples and questions.
- Bring your observations to a professional conversation.
