The picture you see here is Rileys' at home monitor for her heart rate and O2 level. This WONDERFUL piece of machinery has two volume levels when either her heart rate or her O2 drops, LOUD and O.M.G. the kid needs a transplant! Needles to say the first night. . . . not soo much sleep. They are both doing great. Riley just needs O2 for a little longer and Kayden, well, lets just say that he no longer has the protective sweater around his tallywacker.
