These are my very favorite diaper covers! They are so sturdy (which makes them perfect for wiggly sleepers), but they remain flexible and soft to allow children a full range of motion. They are very easy to use and clean. Ease of Use There's nothing to it - just put the prefold inside the cover and put on baby just as you would any other diaper! I actually think they're a bit easier to use than a disposable diaper because of their sturdiness. Disposables are sometimes a bit slippery and flimsy, or they can be prone to tearing if you are wrestling with a wiggly child. These diapers do not carry that risk! Leak Prevention We have never experienced a single leak with Bummis after 1.5 years of use! Comfort They are very comfortable for my son, but we prefer to use them during naps and overnight since they are very slightly stiffer than his other covers. Absorbency These covers do a wonderful job keeping baby dry and comfortable!
