I so wanted one of these - Bea's poos are variable, but often like superglue and I must confess to being a bit tired of that aspect now she is 20 months old. However, we are not on mains water, and the pressure is too low to make a sprayer viable. So...I do use the odd paper liner when I know a poo is due, and this has really helped - she is fine with them, and at nursery they use them all the time (which also = pretty clean nappies coming home which at the end of a hard day's work also makes life easier). Somehow just having fewer grim ones makes things so much better. For those that escape this far from poo-tight solution, I try to get big bits down the loo (sometimes there are no big bits, just a zillion smaller sticky bits) and rinse the rest down the sink, wiping around with antibac afterwards. I also bung the whole thing in the loo, leave a corner to grab, and after a few mins it is usually loosened enough to fall off - or most of it.
Now how yucky is that to re-read!
