Although no 2 children develop at the same rate, they should be able to do certain things at certain ages. Learning to sit up, walk, and talk are some of the major developmental milestones your child will achieve.

Here is information about how babies and young children typically develop. Examples of developmental milestones for ages 1 month to 6 years are listed.

NOTE: If you see large differences between your child’s age and the milestones listed, talk with your child’s doctor.

Well-Child Visits

Remember to take your child to his recommended well-child (health supervision) visits. At each visit, your child’s doctor will check his progress and ask you about the ways you see your child growing.

The American Academy of Pediatrics recommends regular well-child visits at the following times:

• Before your baby is born (for first-time parents)
• Before your newborn leaves the hospital
• Within 3 to 5 days after birth and within 48 to 72 hours after leaving the hospital
• During the first year after birth: visit by 1 month of age and also at 2, 4, 6, 9, and 12 months of age
• In early childhood: visit at 15 months, 18 months, 2 years, and 2½ years of age as well as yearly visits from 3 to 4 years of age
• In middle childhood: yearly visits from 5 to 10 years of age
• In adolescence and early adulthood: yearly visits from 11 to 21 years of age until care of your child changes to an adult-oriented physician

Your pediatrician may recommend additional visits. If you have any questions or concerns about your child, talk with your child’s doctor. If there is a concern, early treatment is important.
