He will sleep better if you give him somewhere to sleep and ask him to be there.
If he has space, he is more likely to want to use it and not relax.

Well I don't want to lock him up in the shed. He is using his kennel now which is good, before he would sit on top of it lol. He has been good for these last few nights which is relaxing. Thanks for everyone's help

Oh I forgot...Is getting bones good for him? I didn't think it is a good idea cause he is a bit of a leg nipper so I thought it would encourage him..

Having bones to chew on, won't encourage leg nipping.

In fact having something like a bone / toys that's his, that are allowed activities are necessary to replace the playful nipping behaviour you dislike.

You must have the behaviours you want in mind, so you can encourage those, not just be negative when he's doing something you would rather he didn't. Reards can be training treats, praise, or fun games he likes.
