I use cloth diaper and there's almost no leakage. I tried disposable before and theres always leakage around the waist area. if you keen on using disposable u can try to put a diaper cover over it so it wnt leak. if u r planning on cloth diapers I highly recommend alva baby. its affordable and user friendly. I dnt pre soak my diapers. just collect enough (about 30 or so), use 95 degree water to wash it. I also add vinegar and baking soda for sterilization.
