One Size Reusable Diaper Cover (Adjusts SMALL-MEDIUM-LARGE in the same diaper) with One Natural Bamboo insert, Change only the pad every 2-5 hrs depending on the urination pattern and keep the same Diaper Cover for a second use for the day, after wiping the inner portion. If we buy it for new born, this will last till the baby crosses 3 years of age. Preferred by mothers mostly as an excellent day time diapering option for babies under 1 year. More mothers prefer to use a Bumberry Diaper Cover with natural Bamboo Insert as a solution for high skin sensitivity and allergic to disposables. The Bumberry Wetfree Microfiber Insert is also an excellent option with the Bumberry diaper cover as the insert has a wet-free suede microfleece fabric on the skin facing side of the insert that keeps the baby bottom dry. Please check out for BUMBERRY Pocket Style Diaper as an excellent overnight diapering soluttion and any-time diapering solution for babies over one year of age.
