I think this sounds like a conflict between honeymooning and non-honeymooning Type 1s… Most non-honeymooning Type 1s would not want a system where insulin could just turn off and stay off for hours at a time. There is no way I would trust a system that could shut off (virtually) all insulin delivery for six or nine hours at a time. That is just asking for DKA for me.
I wonder if in a few years when Liam is older, not honeymooning anymore, and less sensitive to insulin, and there are better CGM systems and algorithms and maybe better insulin as well, whether you’d feel more comfortable at that point. Technology is changing SO fast…it’s hard to tell what things will be like even ten years down the road.
