I have three children. One was in disposables only, my middle child was in disposables until a year old- then we switched to cloth (which she is still in,) and my youngest has only ever worn cloth. I will never go back. We stayed at my mom's one night unexpectedly and I didn't have enough cloth diapers to last. My husband ran and bought a small package of Pampers to use. BOTH of my kids woke up with leaks. The next day my son had a horrible blow out in the disposable. It was everywhere. In the 1.5 years I have done cloth I've never had poop leak or come out of the diaper.
I have tried both and personally, I prefer BG diapers over disposable! Sometimes diapers can delaminate, but they are easy to fix. In the long run, cloth diapers are much cheaper than disposable and much more absorbent as well!
