Thanks everyone, I think I might just have to wait until DF gets home from work and do it then. I am finding it so hard to get him to sleep lately, I dont want to risk it waking him up.

Sambo - I seriously considered taking it upstairs or in the loungeroom and putting him in his cot.

Nelle - Where can I get earmuffs? I've looked in the shops but haven't been able to find any. Haven't looked online though.

The vacuum bothered him the first couple of times I used it, although nowhere near as much. When he was younger he didn't care about the bath emptying, now he hates it. I had just put that down to not having used it in a while - we were taking him in the shower with us - but maybe it's related.

If anyone else has any other suggestions I'd be most grateful
