Each child is unique. It is therefore difficult to describe exactly what should be expected at each stage of a child's development. While certain behaviors and physical milestones tend to occur at certain ages, a wide spectrum of growth and behavior for each age is normal. These guidelines are offered as a way of showing a general progression through the developmental stages rather than as fixed requirements for normal development at specific ages. It is perfectly natural for a child to attain some milestones earlier and other milestones later than the general trend. Keep this in mind as you review these milestones.

If you have any concerns related to your child's own pattern of development, check with your pediatrician or family physician.
