Developmental Milestones

What are Developmental Milestones?

Most infants, toddlers and preschool-aged children develop on a predictable schedule. We expect them to perform certain behaviors or tasks by a certain age. These are called “developmental milestones.”

The four main types of developmental milestones are:

  • social/emotional
  • language/communication
  • cognitive (learning, thinking, problem-solving)
  • physical

Every person develops at their own pace. But these milestones can give you important information about your child’s early development.
