DD has been low today for the last 3 1/2 hours. She woke up at 100 (5.5), had the "usual breakfast" and usual bolus 4 1/2 hours ago. She was in the 30's (high 1's to low 2's) for the first 1 1/2 hours and it took 180 carbs altogether to get it to 70 and keep it there. She turned off her basal 3 hours ago. She just dropped again to 62, had another 100 carbs and is currently at 90 (5). This happened several times at night when she was going through puberty, but this is a first to happen in the morning. She has been exercising a lot lately, but her last activity ended at 5 pm yesterday. She is showing no signs of illness. She is expecting her period in about a week. I think I recall Connie saying she has to shut off her pump sometimes. We just received the new Enlite sensors yesterday, but she has not inserted one yet, so no CGMS history. Hoping someone has insights to share.
