9 Months

Discover tips, tools, and support for this age

Your baby takes in information by touching, watching, and playing. Every moment you spend with them is a chance for them to learn! Around this time, your baby may point at objects and people, play games like peek-a-boo, and crawl around the house. They’ll also sleep a lot—up to 14 hours per day!

Scroll down to learn more about your baby’s development, get support for your family, and find free activities to go to together.

Brain Building

Learn through life's everyday moments

When changing your child's diaper, describe the steps you're taking: "First you lay down. Then we take off your pants. Now I unfasten your diaper" Pause after each so they can lift their bottom or move their legs to help.

See what your child is learning

Your step-by-step description invites your child to focus on the details of diaper changing. Your pause helps them to practice waiting and self-control. These are important thinking skills they will use to learn in school and life.

Milestones

Skills babies develop as they play, learn, speak, act, and move are called milestones. Learn about milestones to help you understand your baby's development and act early if you have concerns.

    • Have favorite toys

    • Understand "no"
    • Make different sounds like "mamamama" and "babababa"
    • Copy other people's sounds and gestures
    • Use fingers to point at things
  • Learning

    • Watch an object as it falls
