Developmental milestones are skills or activities that most children can do by a certain age.  While all children develop at their own pace most milestones are reached around the same age, or age range.  Developmental milestones are a great way for a parent and pediatrician to follow a child’s developmental health.  Milestones are often broken down into 4 categories – communication/language, gross and fine motor, social/emotional, and problem-solving.

Developmental and Autism Screening 

Your pediatrician will be following development and milestones at all routine well baby visits along with some other specific screens for developmental disorders such as autism.  The American Academy of Pediatrics recommends all children have an Autism screening at 18 and 24 months of age.  

  • Catching signs of abnormal development early is important so treatment such as physical or occupational therapy, or referral for further evaluation/testing can be started promptly when indicated.  

If your child is not meeting multiple milestones for an age category make sure to discuss it with your pediatrician.
