Answer 1

Since the child has bow legs and has not improved after vitamin D supplements, it is unlikely to be vitamin D deficiency. Besides the alkaline phosphatase is not high and phosphorus is on high normal range. Rule out other causes such as renal osteodystrophy, RTA. Get a 25 hydroxy vitamin D levels done. Also this could be physiological bowing if it is not severe.
