Jacob breaks out badly from the Dex sites. I have tried a Tough Pad under the site with various dressings over the top. They don't hold. Once the site starts to get a little loose, he gets a rash. I'm hoping that if the site stays really stuck, he won't break out. God, I hope this works. I think it is the last chance. The worst part is that the receiver showed ???. I gave it time to recover but it didn't. I did a restart. It still read ???. I did another restart. It started reading but read way high and took many calibrations to get a good read. It's reading good now.
