A bit of backstory ... Last year we bought an cot but DC was too small for it and would not sleep in it due to there being so much space. We used a next 2 me crib and DC has only just got too old for it at 9mo due to sitting, crawling and standing in it.
Anyway, our home was originally built in the early 1900s and we got a lot of problems with humidity due to double glazing holding it in (as soon as the windows are closed after being open, it boxes it in again). We managed to solve the issue permanently now but in December, I noticed a musky, damp smell and looked everywhere. Some of our walls had grown mould in weird places you wouldn't think condensation usually grows (like inner walls at skirting height) and when I looked for something under the cot on a separate occasion, there was a whole layer of mould (it looked like someone had built sand dunes on it, growing downwards from the cot). We'd never noticed because we'd pull the cot out to hoover and never needed to look under it. I pointed it out to DH and said he'd have to take it down and get rid of it.
It turned out it was only growing on the bottom ply where it wasn't treated wood. Now DC needs to be moved into a cot, DH wants to make a complaint because he said lots of people have old homes like ours and the ply should also have been treated/external ply for this reason. I told DH he was being ridiculous and that we have two options, as we kept the rest of the cot to try to obtain another part for the cot from the store we got it from (somehow I don't think it's going to be easy to just pick up the ply as a spare part because it specifically has to fit this cot) or buy a new cot.
DH is still saying he wants to complain about it, refuses to even explore the option of buying a new cot and is really annoyed. I don't think IABU, am I?
