Your child becomes a toddler on their first birthday, and that stage lasts until their third birthday. As they grow, they’ll learn and develop new milestone skills and abilities. Those milestones can help you track your child’s development. Your child’s provider can also use them to guide you and your child along the way.

Tracking what your child can do can help detect specific needs and medical conditions early, often when they’re easier to treat. Your child’s pediatrician will ask you about them at well-child visits, and you can also bring them up if you have concerns or questions.

Not all toddlers reach every milestone at the same time, and that’s okay. Children grow and develop at their own pace. If you have any concerns about what your child can or can’t do, talk to their pediatrician or other provider. They can screen for medical conditions or developmental delays and let you know what steps, if any, are needed.
Toddlerhood is an incredible time of growth, exploration and discovery — for both you and your child. It’s normal to have questions or wonder if your child is hitting milestones on time. Every child develops a little differently, and small delays aren’t always a cause for concern.
