How do you stop the tamper light from blinking on the baby doll?

My sister brought home a fake baby doll that cries. I accidentally did something that made the tamper light go on. How do I undo that? Please help. My sister is going to kill me if I don't fix this problem.|||are you talking about the things they give you at school? the teacher will most likely have to reprogram it. hopefully your sister doesnt get in ttrouble for it. you could try writing a note explaining that it was your fault, and you are not sure what you did. and maybe she will accept that and let her redo it instead of giving her a bad grade.
