It’s common for newborns to have unsteady vital signs or spend time in the NICU. While most of the time they will be just fine, many parents lose sleep worrying about their baby sleeping in another room. For these situations, I recommend the Owlet. It’s a heart rate and oxygen monitor in the form of a “sock” that you put on your baby’s foot. This way it’s not wrapped around the torso and interfering with their sleep.
This product is not cheap, but the comfort it provides mom and dad can help everyone get a good night’s sleep.
