The Born Smart Newborn diaper is an organic AIO diaper that fits most babies 6 -16 lbs. The interior of the diaper boasts 3 layers of organic cotton sewn in to the diaper and an additional 4 layer snap-in insert (included). The unique design allows for easy cleaning and quick drying, with enough absorbency to grow with your newborn. This diaper also has one rise setting, an umbilical notch, and a hidden pocket under the lining to add additional absorbency if needed. Additionally, the snap-in insert can later be used as a doubler in a larger/one-size diaper.
