The best spot for my daughter (age 4) to wear the Dexcom sensor is in her arm, and we've had 2 sensors fall out when the tape became unsticky. Putting on more crap (tape, etc) was annoying.
I found this site www.bands4life.net
and got one for her. This seems to keep it on now, and if it ever did come off and we lost the transmitter I'd be sick! Also, I didn't realize this bothered her, but when we but the pretty bandforlife on her arm, she said, "Yea! Now the girls (at dance) won't ask me 'what is that??' anymore!!" I suppose if you don't know what a CGM sensor is - it does look weird!! Poor kid, I didn't know she was embarrassed by it.
Now if only I could sew I'd make my own bands4life.....time to hit up grandma.
Just thought I'd share. Maybe someone else out there may find a use for this.
