Developmental Milestones are skills or age-specific tasks, like smiling, walking, talking and waving bye-bye, that most children of the same age can do.
Each child develops at his/her own pace and therefore there is a wide age range for meeting milestones. Milestones met within this range are considered typical or within normal.
If your child is unable to perform the tasks or skills and is beyond the typical age range, don’t wait. Contact your child’s doctor right away to discuss your concerns and ask for an evaluation.
