Hey sam, sorry I never got a chance to add you to my MSN - been flat out here

I'd recommend GF (genesa forge) super super trim nights - they are really absorbent and very trim. However, even my super pee machine (DD1) out pees them - she outpees everything, so I put her in a fleece suit to sleep in, so at least it doesn't go through onto her mattress. So another option is to grab a few fleece or wool covers and put them over the sposies and see if that works first. Cheaper anyway
