Question

Quizplus · Accepted Answer

At 4 months old, babies have developed the inner ear structures necessary to provide cues to maintain balance, but their muscles are not fully developed enough to keep their balance on their own. Visual cues may also play a role, but the inner ear cues are considered more important for balance maintenance. Blindfolding would likely make it more difficult for the baby to maintain balance, but they would still have some use of their inner ear cues.
