[0001] This application claims priority under 35 U.S.C. .sctn. 119(e) to U.S. Provisional Application Ser. No. 60/664,769, filed Mar. 24, 2005, which is expressly incorporated by reference herein. BACKGROUND [0002] The present disclosure relates to juvenile relaxation apparatus, and particularly to juvenile bouncers, rockers, loungers, cribs, cradles, and bassinets. More particularly, the present disclosure relates to systems for imparting rocking motion to a frame while a juvenile occupies a seat carried on the frame. SUMMARY [0003] According to the present disclosure, a juvenile relaxation apparatus is provided with a side-to-side rocker motion system. The juvenile relaxation apparatus includes a juvenile holder configured to hold a juvenile, a rocker blade coupled to the juvenile holder, and a "side-to-side" rocker motion system coupled to the rocker blade. Illustratively, the juvenile holder includes a seat for holding a juvenile and a frame coupled to the rocker blade and configured to support the seat in an elevated position above an underlying floor surface. [0004] In illustrative embodiments, the juvenile relaxation apparatus is a bouncer including a rocker blade that is coupled to a flexible seat-bouncer frame configured to support an elevated seat. The rocker motion system is operable to produce side-to-side rocking motion of the rocker blade and the flexible seat-bouncer frame coupled to the rocker blade. In use, a juvenile seated in the seat is free to bounce the flexible seat-bouncer frame supporting the seat up and down during side-to-side rocking motion of a bouncer unit including the seat and the flexible seat-bouncer frame. [0005] In illustrative embodiments, the rocker motion system includes a stationary floor base and a drive linkage. The stationary floor base is coupled to the drive linkage and is configured to extend through an aperture formed in the rocker blade to contact the underlying floor surface. The drive linkage is located in a chamber formed in the rocker blade and is configured to use rotation of a motor-driven rotatable drive shaft included in the rocker motion system to rock the rocker blade (and the frame coupled to the rocker blade) from side to side relative to the stationary floor base. [0006] In other embodiments, the juvenile holder comprises a bassinet, a lounger, a hammock, a cradle, or other means for supporting a juvenile in a seat on a frame. In each embodiment, the juvenile holder is coupled to a rocker blade that is coupled to a rocker motion system. [0007] Additional features of the disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived. BRIEF DESCRIPTION OF THE DRAWINGS [0008] The detailed description particularly refers to the following figures in which: [0009] FIG. 1 is a diagrammatic view of a juvenile relaxation apparatus in accordance with the present disclosure showing a rocker blade coupled to a juvenile holder comprising a seat and a frame and to a rocker motion system; [0010] FIG. 2A is a perspective view of a bouncer having a rocker motion system in accordance with the present disclosure in a "side-to-side rocking" mode owing to rotation of frame kickstands mounted on opposite ends of a rocker blade carried on a seat-bouncer frame to retracted positions alongside the ends of the rocker blade; [0011] FIG. 2B is a view similar to FIG. 2A showing the bouncer in a non-rocking mode owing to rotation of the two frame kickstands to extended positions to steady the rocker blade relative to the underlying floor surface to inhibit side-to-side rocking of the rocker blade and the seat-bouncer frame; [0012] FIG. 3 is an enlarged partial front elevation view of the bouncer of FIG. 2 upon movement of both frame kickstands to the extended positions and showing projection of first, center, and second feet included in a "floor base" mounted in the rocker blade through openings formed in a bottom portion of the rocker blade to engage the floor underlying the rocker blade; [0013] FIG. 4 is a view similar to FIG. 3 showing side-to-side rocking motion of the rocker blade and the seat-bouncer frame to the "left" (relative to the stable floor base) to assume a "left-tilting" orientation; [0014] FIG. 5 is a view similar to FIGS. 3 and 4 showing a "first stage" of side-to-side rocking motion of the rocker blade and the seat-bouncer frame "back" to the "right" (relative to the stable floor base) to resume a "level orientation" as shown earlier in FIG. 3; [0015] FIG. 6 is a view similar to FIGS. 3-5 showing a "second stage" of side-to-side rocking motion of the front rocker blade and the seat-bouncer frame further to the right (relative to the stable floor base) to assume a "right-tilting" orientation; [0016] FIG. 7 is an exploded perspective view of illustrative components included in a rocker motion system located inside a chamber formed in the front rocker blade that is coupled to the seat-bouncer frame and showing spaced-apart top and bottom shells that cooperate to form the rocker blade and showing (from bottom to top between the bottom and top shells), a blade vibrator, a floor base (contained within a phantom perimeter line) including spaced-apart first and second feet arranged to project downwardly through foot receiver channels formed in the bottom shell to set on a floor underlying the rocker blade and a foot foundation adapted to be coupled to the feet and formed to include a rounded center foot arranged to project downwardly through a central opening formed in the bottom shell, and a rocker blade mover (positioned above the floor base and contained within another phantom perimeter line) including a motor housing adapted to be anchored to the rocker blade and a blade mount tilter including an eccentric disk cam coupled to a rotatable cam shaft rotated by a motor (not shown) located inside the motor housing and adapted to move in a "U-shaped" cam receiver formed in the foot foundation of the floor base (as suggested in FIGS. 11-22) to cause the motor housing and the rocker blade coupled to the motor housing to rock from side to side relative to the floor base as suggested, for example, in FIGS. 3-6; [0017] FIG. 8 is another exploded perspective view similar to FIG. 7 showing coupling of the first and second feet to the foot foundation to form the floor base, first and second oblong openings in the bottom shell into the first and second foot receiver channels, the central opening formed in the bottom shell to receive the rounded center foot included in the foot foundation, and two spaced-apart post retainers extending downwardly from an underside of the top shell to help retain the motor housing in a fixed position coupled to the top and bottom shells of the rocker blade so that the rocker blade will rock back and forth relative to the stable floor base in response to rocking motion of the motor housing relative to the floor base; [0018] FIG. 9 is an exploded perspective assembly view of components included in a motorized cam shaft rotation system located inside the motor housing and showing (on the right side) the eccentric disk cam provided on a right end of the rotatable cam shaft and showing (on the left side) a momentary contact switch above a rotatable switch-actuation cam adapted to mount on a left end of the rotatable cam shaft for providing additional power to the drive motor (inside the motor housing) after the rocker blade mover is "shut off" so that the cam shaft will continue to rotate causing the motor housing to continue to rock relative to the stable floor base until the seat-bouncer frame comes to rest in an upright/level attitude; [0019] FIG. 10 is a perspective view of the bouncer of FIGS. 1-9 showing each of the first, center, and second feet of the stable floor base extending through openings formed in the bottom shell of the rocker blade; [0020] FIGS. 11-22 show rotation of the cam shaft to cause movement of the eccentric disk cam that is constrained to remain in the U-shaped cam receiver formed in the foot foundation to produce side-to-side rocking motion of the motor housing and the rocker blade relative to the floor base while the floor base is retained in a non-moving, stable position relative to the underlying floor owing to engagement of the first, center, and second floor base feet projecting through openings formed in the bottom shell of the rocker blade against the floor underlying the rocker blade; [0021] FIG. 11 is a sectional view taken along line 11-11 of FIG. 1 showing the first, center, and second feet of the floor base in contact with the floor underlying the rocker blade and showing that the rocker blade has moved relative to the floor base to assume a "first" upright level attitude shown in FIG. 3 in response to rotation of the eccentric disk cam on the cam shaft to assume a "6 o'clock" position in the cam receiver formed in the foot foundation;
