Today is my daughter's 7th day on wearing the G4. I have to say, on the whole, it's been great. It's made me a lot more aware of post meal spikes - some are crazy high, some are negligible. That alone makes me scratch my head. She had a couple of evenings where it took me until 1:00 a.m. to get her in range, but even though those days stunk, it was nice to have more knowledge of what was happening in between finger sticks. I would say the negatives are: I wish the range were longer, and it has made me slightly obsessed with the numbers. Especially when she's high. I am constantly checking it to see when she turns to head back down. I'm trying to be careful with not over treating with insulin, but it's harder than it was with just finger pricks.
