Jim was my hero today. I found a wet patch in the nuts bed awhile ago, I dried it out but I found it was not only wet again, but mouldy. I realised the sponge mattress (we got it before potty training) had sucked up his nuttly sweat and mould was feasting through his mattress and I was very upset. Even tho he was working late today Jim went to ikea in his was home to get a proper mattress which the nut declared very comfy.

And expensive.
