A 12-year-old girl with vitamin D deficiency has been told that her condition could have been caused by using strong suncream.
Tyler Attrill used factor 50 cream which, according to her consultant, could have deprived her of the essential vitamin and caused the bone disease rickets.
BBC Breakfast's resident GP Rosemary Leonard gave her advice for sun exposure.
