Ewans sleeping habits have not changed

I was busy in the computer room and thought it was a little too quiet in the lounge. Once I emerged, I found Ewan asleep on Brads back, whilst Brad was reading his Cruizin magazine. Now we are not necessarily shocked when we see Ewan sleeping in weird positions but it can't have been that comfortable. He has always been the same, once he is tired that is it.....he is asleep regardless where he is. He has fallen asleep on me whilst at Fasta Pasta and the Royal Hotel. Hence, he sleeps when he's tired.
