What are the symptoms of child with diabetes?

Drinking and peeing. Kids with type 1 diabetes will have to drink and pee a lot. This is especially noticeable when it happens overnight causing disrupted sleep. Some may start wetting the bed again. Many kids are also hungrier and lose weight before diagnosis.

3 poly's -- Polydipsia (drink a lot), polyuria (pee a lot), polyphagia (eat a lot). If advanced, confusion, rapid breathing, and coma are possible.
Depends on the type. Increased thirst and urination, even unintentional weight loss can be typical of type 1 diabetes, but type 2 can be more subtle. A positive family history is for t2dm is an important "symptom", acanthosis nigricans (dark discoloration of the skin in folds of neck or arm pits) can be seen, weight gain and --yes-- frequent urination and thirst.
