I've noticed your name on here loads MMH - I didn't know you lived in Barnsley!
Well, ds has so far eaten a piece of poo , peed in my trainer, peed on the leather sofa, luckily I have oodles of sheets covering the carpet. When I put him down for his nap this morning I just covered his mattress with a few towels, the wee soaked through to the mattress - it is semi-waterproof, if that makes sense! Anyway, I cleaned down the white mattress with a few babywipes and they were black - the mattress honestly does look white, I can't believe how filthy it is! This led to a whole massive wash down and so ds is still having to nap on a load of towels, despite now having a nappy on, because teh mattress is wet!
