Developmental Milestones

NOTE: As a parent, you know your child best. If your child is not meeting the developmental milestones for his or her age, or if you think there could be a problem with the way your child plays, learns, speaks, acts, and moves, share your concerns with your child’s doctor. Just as importantly, tell your child's doctor if you are overwhelmed and think you cannot cope with your child's behavior. Don’t wait. Acting early can make a real difference! For more information, go to Learn the Signs. Act Early.

These milestones and stages of development are presented according to the ages at which children generally reach them, according to the American Academy of Pediatrics. They are included to help you anticipate and understand your child's behavior at various stages of growth. Remember, each child is unique. Since each child develops on his individual timetable, your child may be ahead of, at, or behind the statistical average. 

Remember: Generally speaking, girls often reach these milestones before boys do. Many behaviors that seem unique to a particular age may repeat at a later age. For you, this means your efforts to teach a behavior to your 3-year-old may have to be repeated when she reaches age 6. But take heart. Because you began teaching her patience when she was 3, it will be easier to manage her impatience when it reemerges at 6, for example.

  • What amazing new miracles happen in this early childhood period, as they do in that first year!  Your child’s moving around her world—scooting, crawling, walking and then running, running, running as fast as she can—is the way she explores and gains increasing independence. And imitation is the way your child expresses sounds and physical gestures.

    Finally, your child can “use her words” and ability to express herself to tell you what’s on her mind! This is good news…and can be tough to handle, when she pushes back, tests limits and wants her own way—all normal behaviors! We give you a playbook—on how to be what we call a “Family Manager” in this developmental stage on each page of Behavior Checker.

    Because children in this age group grow and progress rapidly, you may anticipate and analyze how your child is reaching developmental milestones such as walking, running, expressing her emotions, talking, and socializing—and pushing limits, of course. Behavior Checker helps you learn how to respond to these normal, but frustrating, behaviors that your child uses in the first four years of life to discover the rules, limits, and boundaries she needs and wants. But if you have concerns about how your child is developing, talk with your healthcare professional.

  • You may not be thinking about the first four years of your child’s life as leading to “middle” childhood, but it is fun to think that she has reached this awesome milestone by the time she is only 4 years on the planet! She puts into practice all that you have taught her in the first four years, as shared in Behavior Checker—self-discipline, problem-solving, empathy, ability to tolerate frustration—and builds on them to strengthen her ability to get along with you and prepare for the teen years ahead.

    We call these the “Travel Agent” years for you, as you increasingly take your child to places where she explores her world outside of your home, neighborhood and her early childhood education, preschool or daycare. Your efforts in being a consistent caring, supportive and protective teaching parent for the past 4 years make a difference in your child’s developing these skills—communication skills, sensitivity to others, how to form positive peer relationships, and how to balance personal responsibility with independence—and practicing them more in these years. These attributes will help her cope with the stresses and potential risks of adolescence.

    Try to appreciate the individual maturity level of your child. Then celebrate your child’s evolving independence by granting new privileges, as we have talked about in each of the situations in Behavior Checker. When you match each new entitlement with a new responsibility, you show your respect for your child’s growing capability to contribute to your family and the community. Middle childhood is also a period when children become increasingly exposed to the world outside of your family through school and extended social interactions. It may be hard for you to give your child more and more independence, but doing so as she demonstrates her ability to handle more freedom is the name of the game. Behavior Checker reinforces these teachable moments—and is here to help you do so, too!

  • Ah…the teenage years—what we have called “Volcano Dwelling” years for parents. Adolescence is an ever-changing experience, as is most of childhood development. Teenagers differ widely in their physical, social, and emotional maturity because they enter puberty at different ages, progress at different paces, and experience different challenges. 

    Viewing adolescence in stages—early adolescence (11–14 years of age), middle adolescence (15–17 years of age), and late adolescence (18–21 years of age)—yields a better understanding of physical and psychological development and potential problems. Depending on your personal cultural expectations for independence and self-sufficiency, you may view the nature, length, and course of typical adolescent development differently from your teenager. Talk with your teen’s healthcare professional about how you view this stage of life and potential conflicts between your family’s values and culture and those of your adolescent.
