Final answer:
Physiologic bowing is frequently seen in toddlers under 2 years of age.
Step-by-step explanation:
The correct term is "physiologic" bowing, which is a common and typically temporary condition observed in toddlers under the age of 2. Gait, or the manner in which toddlers walk, undergoes developmental changes during their early years. Physiologic bowing refers to the natural and expected curvature of a toddler's legs, where they may appear slightly bowed. This condition is considered a normal part of their development and tends to resolve spontaneously as the child continues to grow. It is essential for caregivers and parents to be aware of these age-related variations in gait to distinguish normal development from potential abnormalities.
