Understanding sleep quality indicators

The Dream Sock automatically tracks your child’s sleep session. This includes awake time, lightly sleeping / restful, and deep sleep. We calculate this using two main points of data: movement and heart rate.


When your child is moving and we cannot get readings, the live sleep quality indicators will indicate the child is active.


Movement can impact the quality of sleep. It is natural for babies to move while sleeping, but extended movement may indicate poor sleep.

Heart Rate

Heart Rate is indicated as beats per minute (BPM). Baby’s heart rates are naturally much faster than adults.
