Abstract
A child motion device includes a frame that provides a structural support relative to a reference surface and that includes an arm pivotably coupled to the structural support. A child supporting device is coupled to the arm and spaced from the reference surface by the frame. A drive system is configured to move the arm such that the child supporting device reciprocates along a motion path at a frequency within a range from about 0.37 Hz to about 0.62 Hz. In some cases, a further drive system is configured to oscillate the child supporting device generally along the axis of rotation at a frequency in a range from about 2.85 Hz to about 3.15 Hz.
