Hi, I am worried about my 7 year old ds. He has woken up a few mornings in the last month feeling shakey, crying and having no energy to the point he has shuffled downstairs because he feels so drained. After eating he starts to feel better but takes over an hour to feel completely recovered. Last night he had a decent sized healthy dinner and an ice lolly after. He has a decent diet. Probably the healthiest diet of all the kids I know. He has also been complaining of headaches recently. Does anyone know what this could be? I'm waiting a call back from the doctor but that might not be until Monday now. Thanks.
