We are wanting to get a Dexcom 4G. My 10-year-old does not feel any of her lows. Will the Dexcom reduce the number of daily pricks? Currently, we check blood sugar at least 5 times a day. I have heard that with a CGM, you only need to prick the finger once a day, is this true? Also, since our child was diagnosed on Dec 4th, we do a 2AM check for her every night. Will the CGM eliminate the nightly 2 AM check? Can it alert us if she go low in the middle of the night? Thank you. I appreciate any feedback and tips with a CGM.
