MDI is Multiple Daily Injections. Basically shots, but also distinguished from shots with older insulins that only required 2 shots per day but life was lived around diabetes, not diabetes around life.
Dexcom is a Continuous Glucose Monitor (cgm). Medtronic makes one as well. We're very biased after interacting with both company's customer service. They are AWESOME...and sometimes I'd like to run the thing over with a car when I'm sleep-deprived and not feeling rational about just wanting it to be quiet and let me sleep. Every kid (or adult) should be sent home with a cgm at dx. They're that much of a game-changer. If you call Dexcom or look at their website, they will start the process of getting a script from your doctor, contacting insurance, etc. Let them do the work; you don't need more!
You can also call pump companies yourself for trial/information sessions without waiting for a pump class. My daughter actually wore the Medtronic pump/cgm into our intro to pumping class with saline in it. It's important to TRIAL every pump before deciding. They have slight differences that may be a deal breaker for one user, but not another. I'd thought my daughter would choose Animas, but she could feel the boluses and said it hurt. We went with the Medtronic the first time, then later bought a Omnipod PDM through a program called "Cut-the-Cord" that allows her to have it as a back-up or option. She now wears the T-slim, which is her favorite by far. I wish it had a remote, but I'm very excited about the ability to remotely upgrade the pump software, especially as their low-glucose-predictive-suspend is due out in the next few months.
A lot of AP systems will be coming out soon. The Medtronic is already out. I think about 4 more are due out in the next 18 months, followed by at least Omnipod in 2019. That's something to take into consideration, as what you buy will be what you're likely stuck with for the next four years until the warranty is up. For us, that probably means that the first AP my daughter will use will be the Type Zero integrated into her t-slim pump as her warranty won't be up for another two years. But for now, I'm just really excited at even the thought of the low glucose suspend!
We're not feeling like we're dancing right now, either. It comes and goes. Diabetes has thrown lots of curveballs at us in the last couple of weeks: cold, infected site, etc. I turned up basal the night before the ACT as she'd been in the mid-200s all day despite correction doses, only to send her down into the 50s. We were up multiple times, and she went off for the test with four hours of sleep. Then the stress sent her into the 200s. Not what we strive for, by any means, but some days it happens. How sleep-deprived we are really affects how well we cope emotionally with diabetes.
