By what age should a baby typically be able to sit up with minimal support?

At around 6 months of age, babies typically develop the ability to sit up with minimal support. This milestone is part of their gradual progression in physical development, which includes strengthening neck and back muscles, enhancing balance, and improving coordination. By this time, many infants can sit upright while leaning forward on their hands for stability, indicating not only physical growth but also neurodevelopmental progress as they gain more control over their bodies.

Earlier developmental milestones, such as sitting at 2 or 4 months, generally involve more supported positions or require the child to be propped up. By 9 months, while most infants can sit independently without support, the question specifically asks about the ability to sit with minimal assistance, making 6 months the most appropriate answer.
