According to various aspects, exemplary embodiments are provided of reusable diapers. In an exemplary embodiment, a reusable diaper may generally include a forward portion, a rearward portion, a crotch portion, and first and second waist portions. At least a three-by-three array of snap members may be along the forward portion that allows selective adjustment to a functional rise of the reusable diaper. The array may include at least a first row of at least three spaced-apart snap members vertically spaced from and aligned with corresponding snap members in at least two other rows of the array. The first waist portion may have corner regions releasably attachable to the second waist portion. The corner regions may be resiliently stretchable to permit at least some adjustability to a functional waist size of the reusable diaper as defined by the first and second waist portions when the first waist portion is releasably attached to the second waist portion.
