I am so excited my scale at home might be off by +8-10lbs. My son weighed himself on the medical balance scale at the Y today and immediately after at home on our digital scale. He was around 134 at the Y and around 144 at home. I thought maybe the calibration was off on the Y scale but my husband has said he has noticed this when he has weighed himself on scales when travelling. Not getting my hopes up but wouldn't it be nice if I was closer to goal than I thought. Hmm, sounds to good to be true. I don't feel like buying a new scale so I probably won't know for sure until I go to the doctors in mid Oct.
