Hey, my daughter took hers one time when she was 8, and got scared when the thing tightened and she started saying, "Oh no!! Oh no!! I'm going to get stuck" and tugged her arm... you know what the reading was when it beeped?? 274/168!! We left the reading like that and I told her that store personnel are going to be looking for a BODY somewhere after seeing a blood pressure like that! 128 is fine, and the laughing probably raised it to that! Relax
