Skills such as taking a first step, smiling for the first time, and waving "bye-bye" are called developmental milestones. Developmental milestones are things that most children can do by a certain age.
Because children develop at their own pace, milestones are not concrete rules. We can't know exactly when a child might learn a new skill. However, we do know that most children learn skills during a certain time. For instance, most children begin walking between 9 and 15 months.
Milestones are helpful because they let us know what to expect as a child grows. Using the milestones, you can track how your child is learning new skills.
If you are worried that your child is not meeting a milestone or you have concerns about your child's development, don't wait. Talk with your child's doctor or teacher. You can also call Help Me Grow.
