Hi. My 2.5 year old daughter is drinking lots and lots - yesterday she must have had about 3-4 litrew of squash. She can sit and drink a whole drinks container straight down. I don't think this is normal - I read that drinking a lot can be a sign of diabetes - have I lost it or shoud I ask the doctor ( wioll be a 3 day wait) - and they will then think I am mad. What could this be? Thanaks
