Yes yes I'm sure there's a bit of PFB about it but here goes.
We're going to have DS take his naps at the ILs occasionally. They've got a cot there which has been used by the other GCs. So mattress is probably about 7 years old.
I want DH to check how old the mattress is and if it is as old as I think, either buy a new cover or buy a new mattress. Main reason being SIDS and possibility of mould spores inside the mattress (FIL has said there is damp in the room that the cot is kept).
I don't want to make a big deal of this, but would like a new cover at least.
AIBU to ask and AIBU to want to buy a new cover or mattress if it's really old? DS is 1 so I know the risk is minimal now he's older. I wouldn't make a fuss if it was a couple of years old!
