I thought two hours was quick to pee through all those layers - I guess it's the average
The problem is that I don't like to wake him to change him if he's sleeping longer than that - he hates being changed so much and screams and screams. Not a happy nudist at all!
I think I'll make the bodies out of a layer of microfibre snadwiched in flanelette. Then the sides are still thin (at the moment our sides are two layers of flanelette) so they're easy to put elastic into, put the snaps on and not chunky at the sides under clothing. Then I'll make the soaker part out of bamboo I think and use our microfibre boosters with the microfleece top still. I'll make 5 that way and if they work well make another 15 or so. We love our cloth and want it to work the best way possible for our little fella!
