DD has a comfort blanket/bear thing
She has slept with it every night since we took her dummy away, around 11/12 months-ish, she sucks on it so now the poor fucker has no legs and is in a right old state
She also refuses to let me wash him
I have done against her wishes a few times and she has literally sat and watched him spin around the washing machine crying until he came out, then not slept properly for around 3/4 nights afterwards
So I gave up and let her crack on
He hasn't been in the wash for a few years now 
Now the issue is- He fucking stinks!
Really really stinks! If the heating has been on and you go in her room you can smell him! It's grim
Now DD has recently turned 5, I asked her if I could wash bear so he was fancy for her birthday - she said no so I didn't
Now I'm changing the bedding today, and DD isn't here, would I be a heartless cow if Bear accidentally got tangled up in the bedding and had a wash?
I fear it's a matter of health and safety at this point?
