Your child’s experiences in the early months and years of life affect their health and well-being for the rest of their life. Your caring, nurturing, and safe parenting help ensure your child’s healthy development.

Understanding child development can help you know what to expect and what you can do to help your child grow in a healthy way. In the early years of life, your child’s behavior communicates their needs and how they are changing and growing. Listening to your child’s unique cues can help you support them through their years of very rapid growth and development. During periods of exciting development or changes, your child may wake up more frequently at night.

The stages of child development described here are guidelines only, not a set of rules. Every child develops at their own pace. If you have any concerns about your child’s development, talk to your health care provider.
