Try using reusable/washable pads. I would change their pads frequently and it would still leak through and I tried several disposable pads. Now I have the reusable ones and there is no leaking at all as they absorb twice the moisture as disposable ones, wash up nice with no stains and no odors and save you money on pads. I even don't have to change them as often since they absorb so much more.
