The Dream Duo is designed to help parents ensure that Baby develops healthy sleep habits early on and gets a good night’s sleep. The Monitor Duo had features notifying users that Baby's heart rate and oxygen levels departed from preset values. The Dream Duo does not have those notification features. The Dream Duo's prompts are based on sleep quality indicators. The Dream Duo (Dream Sock plus Cam) is here to give parents the tools they need to get a better night's sleep for the entire family!
