My little boy was diagnosed in June of this year and is four. We test about six times a day, once at night, and treat after each meal. We will also treat at night if he is over 210 at his 1 am test. Slowly his AC1 has been dropping and his ave BS is about 200. However it just seems on a daily basis that we are all over the place with BS. Anywhere from 270 in the morning to 45 some afternoons-like we are playing a game of ping-pong. Sometimes we can see it looks like a bit too much insulin, thus will decrease the compenastion dose, only to see he start running too high...sometimes it seems linked to excercise or illness, but other times, I dont see any clear correlation. Some days are just fine though. The endocrinologist didnt say much when I asked if this much variability was common-I would have liked her to say yes or no, and give me guidance about what we are doing wrong. Is this sort of variability normal?
