The most common early signs of diabetes are increased urination and thirst. This is because your child doesn’t have enough insulin to process glucose, leading to high blood-sugar and a reaction where their body pulls fluid from tissues. This makes your child constantly thirsty and in need of bathroom breaks. Other warning signs include:
∙ Fatigue: Your child always seeing tired or drowsy could signal their body is having trouble processing sugar into energy. Extreme instances of this include stupor and unconsciousness.
∙ Changes in vision: Having high blood-sugar often causes blurred vision and other eyesight problems.
∙ Fruity smelling breath: Having breath that smells fruity, even when it’s been a while since your child ate, often means there’s excess sugar in their blood.
∙ Increased hunger or unexplained weight loss: Extreme hunger can mean your child’s muscles and organs aren’t getting enough energy. Any sudden weight loss in your child should not be ignored, but especially when they’ve been eating more.
∙ Changes in behavior: Your child suddenly seeming moodier or more restless than normal while showing any of the symptoms.
Your child having heavy or labored breathing or experiencing nausea and vomiting are also signs of diabetes, but all of these symptoms, regardless of whether or not they are from diabetes, are cause for you to take your child to their pediatrician.

That happened to a friend ‘s child. He was really thirsty all the time and had other symptoms. He took his child to the doctor and found out he had diabetes. He had to give the child a shot every day. it was awful. That was a while ago so I don’t know what they do now for children with diabetes.
