Waddling is a type of walking characterized by a side-to-side motion, often seen in animals like penguins and ducks. This movement occurs when the legs are positioned further apart, causing the body to sway as it moves. Waddling can be a natural gait for certain species, helping them maintain balance and stability. In humans, waddling can occur due to various factors, such as obesity, pregnancy, or certain medical conditions. This gait may indicate difficulty in walking or a need for support. While it is generally not a cause for concern, persistent waddling may warrant a medical evaluation.
