My (almost) 8 year old daughter has had Type 1 for 4 years now and her moods are clearly related to when her glucose levels change. When she is high... she gets SO irritated and angry (which is actually how I knew she had pre-diabetes). It's very sad because I know she cannot really control it. She has been through so much the past three years as well (her father and I divorced and I remarried) and other things that I know can cause extra external stress on her.
All I know to do is PRAY and keep her numbers where they can be the best I know how... any other advice?
