witts - I use disposable bed pads, it's much easier and they are fairly cheap. I buy them from Incontinence Choice on line. As I've mentioned on TP before, I have huge problems with mum's urine output (massive flood, all in one go!) so have tried lots of things to cope with this. I put a large disposable bed pad underneath her (I use the Lille Classic bed pad, 60cm x 90cm), then for overnight, or when I leave her in bed during the day, I wrap a smaller bed pad (I use Viva Medi's Bed Pads Plus 40cm x 60cm) around her left side, which is where, for some strange reason, the leakage always occurs. If her pad leaks, then the smaller bed pad catches it (and sometimes this saves the nightie getting wet too), and if that fails then the bigger bed pad usually holds any overflow. I usually manage to save the actual bed sheets this way. I know it's not very 'environmentally friendly' of me, but life is hard enough without extra things to wash on a regular basis. The disposable bed pads probably do move around more than the washable ones would, as they are flimsier, but I've become a bit of an expert at positioning them! You can also re use them a few times if they remain clean and dry. Eventually they kind of wear thin in places, but I find it works well for me.
