🧸 CDC & WHO milestone checklists
Child developmental milestone tracker
Enter your child's age to see the motor, language, social/emotional and cognitive milestones expected for that band — based on the CDC's "Learn the Signs. Act Early." checklists and WHO motor development milestones. Check items off as your child hits them; your progress is saved on this device.
10–12 months milestones
0 / 7 checked🏃 Motor
- Pulls up to stand; walks holding onto furniture ("cruising")
- Uses a finger to point at things; picks things up with thumb and index finger (pincer grasp)
🗣️ Language
- Waves "bye-bye"; says "mama"/"dada" or another special name
- Understands "no" and simple one-step instructions
❤️ Social / Emotional
- Plays games with you, like peek-a-boo and pat-a-cake
🧠 Cognitive
- Puts something in a container, like a block in a cup

This tool gives an estimate based on published growth/immunization references — it is not a diagnosis and can't replace your pediatrician. Always confirm timing, dosing and any growth concerns with your child's doctor.

How to use this checklist
Every child develops at their own pace — these checklists describe what most children can do by the end of an age band, not a pass/fail test. A single missed item rarely means anything on its own. What's worth a conversation with your pediatrician is a pattern: several milestones missing across an age band, a skill your child had and then lost, or a consistent gap that persists into the next age band too.
These lists are adapted from the U.S. CDC's publicly published developmental milestone checklists and WHO's motor development milestones — widely used parent-facing references, not a clinical screening tool. A formal developmental screen (like the ASQ-3, often used at well-child visits) is more sensitive and should be your pediatrician's call, not this page's.
