I've had the smoke alarm thing many times over the year. It's still nothing compared to the outright FEAR of the baby's heart monitor alarm tripping. When we brought our preemie twin boys home (11 years ago now) they were on heart/lung monitors for several weeks. If they stopped breathing or one of their hearts stopped beating a SHRILL alarm would sound. Well, every time the tape came loose on one of the sensors on either one of them two parents would have their own hearts stop as the alarm sounded and we'd dash into their room ready to perform CPR. It happened over and over again. I think we aged 20 years in 2-3 weeks that year.
