Which of the following is NOT a typical gross motor milestone for a 9-month-old?

• A. Sits without support.
• B. Crawls.
• C. Pulls to stand.
• D. Walks independently.

Answer: (D)

Nine-month-olds are rapidly refining balance and strength, but they’re typically not yet walking on their own. By this age, many babies can sit without support, which shows good trunk control. They also often begin to move around by crawling or scooting, and they may pull up to stand or cruise while holding onto furniture. Independent walking usually comes later, around 12 to 15 months, with plenty of variation among individuals. So walking independently at nine months isn’t typical, while sitting without support, crawling, and pulling to stand fit the expected sequence for this age.
