A crib gate position indicator for use with a baby crib having a movable gate that can be placed into an open or a closed position. The crib gate position indicator includes a first portion that is mounted to the moveable gate and a second portion that is mounted to the frame of the crib. One of these two portions wirelessly detects the presence of the other when the moveable gate is closed. When the moveable gate is opened, the non-detection of the other member activates an indicator, visual or audible, at one of those members to alert a nearby caretaker that the crib gate is open. Alternatively, this indicator can be remotely-located and may even include a speaker for also conveying both a crib gate open condition as well as the sounds of the baby in the crib. Several alternatives of non-contact detection are disclosed for these first and second portions. Also, the crib gate position indicator can be applied for use with hospital beds, or doors and gates in general.
