By about 6 months, what gross motor milestone is typically achieved?

• A. Sits with support
• B. Crawls
• C. Sits without support
• D. Rolls over

Answer: (C)

At about six months, infants gain enough trunk control and balance to sit upright without needing someone to hold them. They may start by using their hands for support or balance, but over the next weeks they can sit with the pelvis stabilized and hands free for short periods. This milestone sits without support is typical around six months, occurring after rolling has established new ways to move and before crawling becomes common. Rolling over often happens earlier, and crawling tends to come a bit later as coordination between arms and legs develops. So, the best fit for this age is sitting without support.
