My child's daily basal requirements have doubled from 15 to 30 units over the course of three months. This seems quite a lot compared to her body weight (35 kg) and I'm a bit alarmed about how quickly the requirement has increased. Yet, her sugar levels often take off during the night and are difficult to control. Should I keep increasing it until the sugar stabilises? There have been no changes in level of activity or anything else. Is this normal; has anybody else had a similar experience?
