This gadget is the only reason I got any sleep for the first 6 after our daughter was born! Owlet camera and smart sock can give you the peace of mind to know your little one is sleeping soundly. Sock and camera record all movement and sleep quality. Heart and O2 sensor monitor helps to make sure they’re safe and well at night, and will alert you via the base if heart rate or oxygen dip too low or too high. Lightly used camera, sock, and Dream Sock expansion sock. Only missing size 3 pink sock, all others unworn. 2 sensors for the first sock, base, cables, camera, mounting and cord mounting equipment unused. Dream sock expansion comes with the 3 socks, sensor, base, and chords. Boxes and instructions included.
