what's that?

this weekend, we went to a little gathering where there were some adorable kids.

after a while, sitting at the kitchen table, the almost 4-year-old touched my dexcom sensor (on my arm) and asked 'what's that?'

'it's a sensor that checks my blood sugar.'

'oh, ok.' ... back to playing.

if only it was that easy to explain to some adults. :)
