3. The parent and child will be given instructions on how to use the study website to complete a questionnaire to obtain the type of bedtime snack to have. The amount of snack and the insulin dose to cover the bedtime snack will be based on the child's usual diabetes management. On six of the nights the child will be asked to eat the primarily carbohydrate snack and on the other six nights, the child will be asked to eat the carbohydrate plus fat snack. The order of the snacks will be chosen at random by the computer. If a drink is needed, the child will be asked to drink only water with the bedtime snack.
