My only suggestion would be to consider the possibility of a pump, perhaps after a short period of CGM (continuous glucose monitoring) in order to better define blood sugar fluctuations over time and the relative infusion dosages. A diabetes team with a solid experience in the field of children and adolescent with type 1 diabetes would be necessary anyway.

[Editor’s comment: You may wish to ask your diabetes team about giving your daughter diluted Humalog for those high blood sugars. This would allow you to give much smaller increments, such as 0.25 unit or 0.5 unit. As for her unpredictable blood sugar swings, it is possible that your daughter is still in her honeymoon phase when her pancreas is still producing “some” insulin. How much and when it will work is unknown. Your diabetes team should be able to tell you more about this phase. You may wish to read the previous questions we have on the Honeymoon.
