Have you ever wondered how your child is growing and developing compared to other children of the same age? How do you know if your child is “on the right track”?

Your child is going through many physical and mental changes. Although no two children grow at the same rate, experts agree there are “normal” signs of development. This brochure will provide you with a checklist of important milestones in your child’s development during the third year of life.

It is a simple tool you can use to be aware of and appreciate the dramatic changes that are occurring in your child. Watch for these signs in your child over a one month period. (Even children have “bad days.”) Remember, each child is different and may learn and grow at a different rate. However, if your child cannot do many of the skills listed for his or her age group, you should consult your pediatrician. If your child was born earlier than expected, be sure to deduct the number of months born early from his or her age. A 5-month-old born 2 months early would be expected to show the same skills as a 3-month-old who was born on his or her due date. Several additional sources of information are listed on the back of this brochure.

You are the most important observer of your child’s development. If your child has special needs, early help can make a difference.
