BuckleyBoo BuckleyDog 12" Green BuckleyBoos encourage cognitive development through multi-stage learning. Stage 1: Matching - Children first learn to scan and match the 3 brightly patterned ribbons- polka dot to polka dot, stripe to stripe. Stage 2: Buckling - At eighteen months, children are ready to buckle, but they cannot yet unbuckle, which makes BuckleyBoo, for a time, a toy to be shared between parent and child. At three years, children have both the physical strength and the problem solving skills to buckle and unbuckle and they will happily do for hours on end. Includes an internal motion activated chime which will delight your child
