On Wednesday night I put my daughter to bed as usual, and an hour later the alarm sounded. I went flying upstairs to find her sleeping peacefully, in a deep sleep but definitely breathing. She had quite a start when I launched at her. That night it went off a further 4 times, once when I had just got back into bed(about 1 1/2 metres away) and could hear her breathing. I took her to the docs who gave her a once over and said her heart and lungs were normal and strong. It went off again this morning but again she was absolutely fine. She is now sleeping through the night, however,I am not as I keep waking up as I have lost all confidence in the device that is supposed to give me peace of mind.
