I be give two of these cover and start use they when I bring my son home from the hospital . although they be a little big , and occasionally leak , I find they provide the best protection of anything I try . he be now six month old and can poop out of ANY diaper , except a cloth cover with a Thirsties cover . I like the new design where both tab have velcro on the outside , so no matter which side I attach first , the other side can layer over the first tab .
