Pick a great brand of cloth diapers and stick with it. So much easier than having a random assortment! Cute, comfy and well-designed, SoftBums diapers have an elastic "drawstring" system built in which is used for adjusting to the size of your little ones legs. The shells can be used as a pocket or 2-in-1 with a snap-in insert called a pod. This pack includes: 4 Echo shells (2 teal, 1 light blue, 1 brown) and all the inserts you need (5 Superpods, 1 medium pod, and 10 small pods). The small pods can be used alone for baby's first weeks or months, then later snapped on as a doubler for nighttime or as needed. Great system.
