Baby milestones by month
Check off what most children your child's age can do, and talk about the rest with your doctor.
Choose the age checkpoint
Pick a child profile and the checkpoint follows your child's age automatically.
The 18 months list shows what most children (75% or more) can do by that age. It is not a screening test, and every child moves at their own pace.
Social and emotional
Language and communication
Cognitive: learning and thinking
Movement and physical development
You checked 0 of 15 items.
The 15 items you did not check are the ones to raise with your doctor.
Talk about the unchecked items with your doctor
This list does not diagnose. Show the items you did not check at your next visit; the earlier something is noticed, the easier it is to support. If you are worried, do not wait for the next check-up — book an appointment.
Next checkpoint: 2 years.
The items come from the “Learn the Signs. Act Early.” list of the US Centers for Disease Control and Prevention (CDC):
This list is not a substitute for a standardized developmental screening tool. If you are concerned about your child's development, talk to your doctor.
About this tool
What is this tool for?
It brings together, in one list, the things most children your child's age can do, across four areas: social, language, cognitive and movement. The items come from the list the US Centers for Disease Control and Prevention (CDC) prepared with the American Academy of Pediatrics. There are 12 age checkpoints, from 2 months to 5 years. Signed-in parents can save their checks and find them again later, and print the list to take to a doctor visit.
How do I use it?
Choose your child's age checkpoint; pick a child profile and it follows their age automatically. Then check the things your child can do. If you are unsure, leave it unchecked: this is not an exam, it is a note for the conversation with your doctor. The checkpoint never rounds up — an 11-month-old gets the 9-month list, because the 12-month items are not expected yet.
How do I read the result?
There is no score and no percentage on the screen, and that is deliberate. The CDC describes these items as things “most children (75% or more) can do by a certain age”, so an unchecked item does not mean a delay. Treat the items you did not check as topics for your next visit.
Limits of this tool
This tool does not diagnose and is not a substitute for a standardized developmental screening tool — that is the CDC's own caution. For children born preterm, age is judged by corrected age, not the birth date. If your child has stopped doing something they used to do, or you have any concern about their development, do not wait for the next check-up — talk to your doctor.
