Never tried this but I am wondering with those disposable diapers being so absorbent and designed to wisk moisture away from the baby's bottom, if laid open on the floor, towel like, for her to lay on (and use) when she needs to go, would help any?   I don't think it would hurt her in anyway, though you may want to check around first as I do not know - but being for a baby, you would think should be fairly safe.
