stress...

My daughter's blood sugar levels rose to 540 this morning. normal is 100-200. The doctor said we gave her too much of a snack last night at bedtime. So we gave her more insulin at lunch. Her numbers have dropped now down to 400. This is still high, but better. My concern now is how I am supposed to watch a 1 year old, 3 year old, and six year old, while I am trying to figure out what is wrong with my other 3 year old and her blood sugar levels.
