Growth milestones for children; Normal childhood growth milestones; Childhood growth milestones

Child development is complex. Any "checklist" or calendar of developmental milestones will blur or miss important aspects, and may trouble parents whose child is developing normally or falsely reassure parents whose child should be evaluated for potential problems.

For every developmental milestone, there is a normal range in which a child may reach that milestone. For example, walking may begin as early as 8 months or as late as 18 months and be considered normal. If you have concern about your child's development, call the child's primary care provider.

One of the reasons for frequent well-child visits to the pediatrician in the early years is to assess your child's development. Any concerns on the part of the doctors, parents, teachers, or childcare providers are important to discuss and address, and may trigger a more detailed developmental assessment.

Below is a general list of some of the things you might see children doing at different ages, but these are NOT precise guidelines. There are many different normal paces and patterns of development. This article provides just one example.
