I've been thinking about a special item I'd like to purchase for this new baby. I'm considering a device called the Angelcare Monitor. Supposedly it detects the baby's movement and alerts you whenever there is no movement for 20 seconds; thus alerting you to any breathing complications, reducing the risk of SIDS. At $100 for a brand new monitor, I really want to do my research to make sure the thing really works and can help prevent SIDS. Do any of you have any experience with this type of monitor?
