The incidence of Type 1 Diabetes Mellitus is increasing annually, in all pediatric age groups, especially among infants and toddlers.However, only 30% of diabetic children manage to achieve and maintain glycated hemoglobin A1c (HbA1c) levels below 8%, although most are treated by intensive insulin therapy.Recently, devices for real-time continuous glucose monitoring (RT-CGMS) have been introduced to aid self management of glycemic control. These devices enable the patients to see the interstitial glucose levels continuously, the trends of decrement and increment, and to have alarms prior to a severe hypoglycemic episode .
