My 12 year old son has been using the MM CGM for just a few weeks now and he HATES wearing the sensor. We fought with the insurance company for 6 months for this wonderful technology and he is refusing to wear it. He says it hurts all the time. He's been wearing the Omnipod for 2 1/2 years with no problems, he loves it in fact. If anyone has any suggestions I would appreciate it.
