Developmental Health Watch

Because each child develops at his own particular pace, it's impossible to tell exactly when yours will perfect a given skill. The developmental milestones will give you a general idea of the changes you can expect as your child gets older, but don't be alarmed if he takes a slightly different course. Alert your pediatrician; however, if he displays any of the following signs of possible developmental delay for this age range.

• Cannot walk by 18 months
• Fails to develop a mature heel-toe walking pattern after several months of walking, or walks exclusively on his toes
• Does not speak at least 15 words by 18 months
• Does not use two-word sentences by age 2
• By 15 months, does not seem to know the function of common household objects (brush, telephone, bell, fork, spoon)
• Does not imitate actions or words by the end of this period
• Does not follow simple instructions by age 2
• Cannot push a wheeled toy by age 2
