I have a relative with a 2 year old child. They have been staying with me and I was concerned to see that he was fed mostly on chocolate or cake. He would be given 3 bottles of chocolate milk a day several chocolate covered biscuits some chocolate bars and often doughnuts and cake and of course lots of sugar coated sweets. The mother says he won't eat proper food so she gives him sugary things for energy. My concern is if this carries on can the child become diabetic? Thank you for your advise.
