My 6 year old grandson seems to be losing weight, has very pale skin, dark circles under his eyes, says he does not sleep well, and I am concerned. He has some allergies or sensitivities to dairy and sugary products, was breast fed until 12 months, has always eaten well and was robust and intelligent, advanced for his years. he seems to look unwell and listless some days. His mother has always been careful with his food avoiding pre-packaged foods full of chemicals and numbers on the labels. He lives on a cattle station in western Queensland with plenty of fresh air and activity. He has had a broken leg when a heavy gate fell on him through misadventure. I see him very regularly. There is cancer on both sides of his family -grandparents. Any ideas? Thank you Jani Allan
