At about what age do infants usually sit without assistance?

• A. 4 months
• B. 6 months
• C. 9 months
• D. 12 months

Answer: (B)

Sitting without support shows developing trunk control and balance. Infants build head and neck control first, then gain the core strength and proximal stability needed to sit up. By about six months, most babies can sit briefly without assistance, using their hands for balance and gradually maintaining an upright posture for longer periods. This milestone marks a transition that also supports reaching, transferring objects, and later crawling or standing abilities. Variability exists, but six months is the typical age for sitting independently. Ensure a safe, supervised environment during practice, since falls are common as infants learn this skill.
