One Size Reusable Pocket Diaper (Adjusts SMALL-MEDIUM-LARGE in the same diaper) with One Microfiber insert. The pocket style stitch design helps to keep the baby to stay wet-free and allow the urine to fully get absorbed into the highly absorbing microfiber insert kept inside the pocket. Preferred by mothers mostly as an excellent Night - Time Diapering option for babies from 6 months to 3 years age. Once the baby starts standing and walking by around 10-12 months, the pocket diaper could be used as an ANY-TIME functional diaper. Check out Bumberry Diaper covers as an excellent solution for infants as they have more urination frequency as they are fed more frequently.
