Normal Development: 18 to 20 Years Old

Each teen is unique. While some behavior and growth milestones tend to happen at certain ages, a wide range for each age is normal. It is okay if your teen reaches some milestones earlier and others later than the average. If you have any concerns about your teen’s development, check with your healthcare provider. Here’s what you might see your teen doing between 18 and 20 years of age.
