Great idea... not quite there
This is bluetooth based and when walking from one side of the house to the other while the baby is wearing the device - it will lose connection and not get reconnected.  In my experience, it required forcefully killing the app to get it reconnected.<br /><br />This is also a bit larger and clunkier than I had hoped and it's a lot for a little baby to sit on.  I was planning on returning the device due to the fact that the bluetooth would disconnect but then in some late night diaper change it stayed with the diaper and that was the end of it.
