From University Heights, Ohio, USA:

My 7 year-old's (Type 1) blood sugar was only 79 mg/dl last night before bed, so we gave him extra food and woke up at 1 A.M. to re-check his sugar. It was 128 mg/dl, so we didn't give him any more food and let him continue to sleep. At what reading must he be awakened and fed more? He is in honeymoon, so he only takes 4 NPH each night before bed.


Different people will have a different blood sugar goal at bedtime and through the night, depending on many factors. I would suggest talking to your doctor about goals for your child.

Some factors to consider would be the following:

  • During the honeymoon period, the islet cells that are still functioning will try to bring the blood sugar down to the normal range. You may find that the blood sugars are even and normal during times your child is not eating (overnight). Sometimes it is difficult to tell the difference between a normal blood sugar and a low reading. For safety your doctor may lower the insulin dose.

  • Consider when the insulins are peaking. If your child takes NPH or Lente in the early evening, checking a blood sugar between midnight and three A.M. would let you know of the blood sugars when the intermediate acting insulin is peaking. The tendency is for the blood sugars to rise during the dawn period after 3 A.M.

  • After the honeymoon period winds down, your experience with your own child will guide you to the safe and reasonable blood sugars to aim for overnight. Many people would aim for readings 100-150 mg/dl.
