We have bought the baby monitor for Jacob which has a sensor underneath the mattress which alarms if he hasn't moved for 20 seconds or longer. Last night the alarm went off, it was awful I was so scared. Somehow Jacob had managed to move himself away from the sensor so it wasn't detecting him at all - he was fine though in a fast deep sleep. I couldn't get back to sleep for ages afterwards though it really did shake me up.
