Thank you for your comments. Your comment is well taken as regards the scoring used for knowledge. A better phrasing in the original manuscript would have been to consider all scores with a mean of + 2 standard deviation (SD) or more as excellent knowledge and all scores with a mean of −2SD or less as poor knowledge.
With regard to the dose prescribed by physicians to infants, the survey addressed the practice of prescribing 400 IU of Vitamin D per day as per the guidelines of the American Academy of Pediatrics.[1] Supplementation with <400 IU daily is considered inadequate.
