Child milestone checklists by age
Wondering if your child is on track? Choose an age for a clear checklist of speech, social, movement and self-care milestones — to print or save as a PDF.
Developmental milestones describe skills many children develop at particular ages. These IDTC checklists cover 6 months to 5 years and help you record speech, social, movement and self-care skills. They are educational guides, not diagnostic assessments or validated screening tests.
Start with the latest checklist age your child has reached. Note what happens in everyday life rather than repeatedly testing your child. Discuss any concern with a qualified professional; seek prompt medical advice for lost words, movement or other skills. The CDC milestone guidance explains why concerns should lead to a conversation and, when needed, formal screening.

Questions parents ask
Are these milestone checklists a diagnosis?
No. They are general guides to typical development. They are not validated screening tests or diagnostic assessments. Discuss any concern with a qualified professional, and seek prompt medical advice if your child loses skills.
Can I print or download the checklists?
Yes. Use a direct PDF link on this page, or open an age checklist and choose Print / Save as PDF. Keep examples and questions to bring to an appointment.
Which age should I choose?
Start with the latest checklist age your child has reached. Do not treat skills on an older checklist as overdue. For a child born prematurely, ask your clinician about corrected age during the first two years.
What is a therapy milestone checklist?
A structured look at what your child can do now in the areas therapy might work on. These printable sheets are developmental checklists — speech, social, movement and self-care. A therapy plan with two or three goals comes after someone has watched your child. How to read them is on our developmental milestone checklists guide.
Where is the 2 year old or 3 year old milestones checklist PDF?
Open the 2-year or 3-year page and tap Print / Save as PDF. They include self-care as well as talking and movement. A three-year-old does not need to read or write their name; that is not a developmental milestone.
