We have made the decision to get a CGM for DS and have ordered the CGM and the Guardian. When I asked about numbing the site before insertion the CDE told me we can't use anything on the site besides alcohol. She said if you used emla or anything like that it could affect the readings. So my question for all of you is: do you use anything to numb the site? My DS is 9 and while he is open to the CGM he is a bit apprehensive about the needle. We currently use Mios which he tolerates just fine but when we tried the silhouette he said it hurt and he didn't like it. I am sure I have read on here that some of you numb the site, do you find that it alters the readings? For those that don't numb it, does your child tolerate the insertion ok? We are using the Medtronic CGM since he is already using the revel pump. Thanks!
