Yep. Sleepover's are tough. The activity and food made it more difficult. And yes we are CGM dependent and the sensor failing put us on DEFCON 1. But what sealed the deal were his actions (or inaction). He was not responding to texts, did not call home when asked (took him 2 hours). We had a plan. It was just looser than it would have been a year ago and gave him a bit more freedom and responsibility. He's just not ready for that level of independence. He was not willfully disobeying, he was just lost in the fun and not paying attention. He got home and told us he hated us and went to bed. As I said, it sucked. But what confirmed for me that we absolutely made the right call (for us at least) was when I went upstairs to check his BG before he went to sleep and asked him why the lancet wasn't in the kit. He said he lost it. I said you gave me a fingerstick BG of 150 when I asked at 11:30pm on the phone. "Oh, that was the last reading on the CGM. I couldn't check BG because I lost the lancet." Hmm. The next day my wife and son picked up his sleepover buddy and had a really fun lunch. It's been a few days. I've taken screen shots of the CGM graph and our text threads. The storm has passed. I'll sit down with him in the next day or so, show him the pictures, and explain why we did what we did. And I'll explain that the next sleepover will work very differently. More discussion with host parents, less trust on our part and more responsibility on his part.
