Thanks - microfibre is what I've used to boost with and I think that might be part of the problem. The success overnight with the haute pockets was with one of the BBH snap out bits, kwim? The bamboo really does seem to help.

I've got him in a fitted with cover tonight, mostly because I ran out of disposables and couldn't bring myself to buy anymore today (it really bothers me when he poos in them, because it's so hard to get into the loo... sorry if tmi!!) Should be OK I think, and if it works well I think I'll try more of them. Might check out some different bamboo fitteds and see what I can find - thanks for the idea about the microfleece to keep him feeling dry That's really the thing which was keeping me from wanting to go for that option.
