The following guideline describes the various physical, cognitive, emotional, and social developmental changes and milestones to be expected during the first year of life.
It is of utmost importance to remember that the timeline is approximate, not absolute. Each child develops at his or her own pace, and some stages may occur earlier or later.
Differences between the timing in this guideline and your child may exist, but do not necessarily mean that there is a problem with your baby's development. Any concerns, however, should be discussed with your physician.
