Depends on where you want him to sleep (as in room I am meaning)
Ash is nearly 7 months and now sleeps in her crate in our room, with the exception of last night, I think OH was obviously feeling cold
as he let her out of her crate once I got into bed
and So the hot water bottle slept on the bed with us
The only downside was I got up at 4.30am to use the bathroom, so she got up - put her out and went back to bed, all was fine until 5.45am when she decided she was hungry
So I eventually gave in at 6am and fed her, now I am wide awake and she has gone back to bed with her dad
no long lie for me this Saturday morning :'
Sorry no tips but just my experience from last night and ours being out the crate - hope that helps
