Final answer:
Asymmetric bowlegs before the age of 2 can be abnormal, but they are relatively common and usually resolve on their own. Extreme bowlegs or those causing pain should be evaluated by a healthcare professional.
Step-by-step explanation:
Asymmetric bowlegs before the age of 2 years can be considered abnormal. Normal legs are relatively straight, while bowlegs show a curvature in the legs. However, it is important to note that bowlegs are relatively common in infants and toddlers and usually resolve on their own by the time the child reaches the age of 3 or 4.
If the bowlegs are extreme, getting worse over time, or causing pain or difficulty walking, it is recommended to consult a healthcare professional for further evaluation and treatment.
It is also worth mentioning that certain medical conditions, such as rickets or vitamin D deficiency, can also cause bowlegs. If you suspect a medical condition, it is important to seek medical advice for proper diagnosis and treatment.
