child is unique. While certain attitudes, 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."
