Hi! The cgm is a marvelous tool in diabetes management; I highly recommend it. We did a year without and would never want to go back. The Share feature wasn't an option when we started using it, and it was/is still incredible. Share allows the kids to have more age-appropriate independence safely. My daughter went half-way across the country at 15 with no one that knew diabetes, and we managed together remotely.
We rely on the cgm to alert us when we need to be up. CGM was so new when we started that our team required I set an alarm as well, but as they and we became more comfortable with the technology, they lifted that requirement. Now people are "looping" and having Dexcom run their pumps and dosing insulin as needed. Several commercial systems will be out next year that use the Dexcom in that manner.
We pay 10% of Dexcom expenses, so $30 per box. We typically get 10-11 days per sensor; they're guaranteed for 7. We tape them extra with Opsite Flexifix or Hypafix so they don't come off.
Was he diagnosed 4/2?
Think Like A Pancreas was my lightbulb after dx. I found it at a library and was thrilled to find an explanation of what the nurses were seeing in the numbers and how they were adjusting doses. When you can breathe, read it. The sooner you're comfortable adjusting insulin for yourself, the better off your child will be. There's no way a dr. or nurse can look at the numbers and know which ones to toss out when making decisions the way you'll be able to. Every number has a story (and every story has a number), and it's important to take the stories into account when adjusting.
I'm sorry you've joined the club but also glad you've found your way here. We've all been in your shoes and are willing to help however we can.
