Moody Diabetes?

My daughter was diagnosed 2years ago-age 14- and is still considered in the "honeymoon stage" This means her total intake of insulin based on body weight is very low (equal to the insulin dose of a 5 year old)because her pancreas is still producing insulin.  We were told the older you are when diagnosed, the shorter the honeymoon period. Average for a 14 year old is 3-4 months. While this saves us lots of money for insulin, it's pretty odd. We were told they like you to be out of honeymoon for at least a year and have your numbers under control before going on an insulin pump. I would really like to get her on the pump before she starts college as an independent adult, and is no longer under my watch. But I guess we will deal with all of this as it comes, because that's what you do with Type 1 diabetes-just deal with what you are given and keep a positive attitude about it all.

We heard someone at the endochrinology clinic mention "Moody diabetes", and that there is a test they can do to see if you have it, but only if the honeymoon lasts over a year. Has anyone else heard of this? If so what is it really called, and what is this test?
