Sorry for your loss. I think I've gone through every emotion known to man reading this thread.
little Archies just learning what attention is I expect. Bless him he is gorgeous.
As for not sleeping high up on your OH when he gets bigger.....uhhhmmmmmmmm my little girlie still does it and she is a grown up girl of 2. Watch the tv with a crick in My neck most evening.
Good luck with him, when you move get a microchip catflap in your bedroom door to let Ella in on her own.
