Sleep.

It's taken Chavo 24 hours to discover how to rest with his halo on. What a challenge this is to both of us. It disorientates him as he bumps into and catches onto things. He's had to learn to drink water from the bowl as his usual habit of water from the tap soaks him as the water fills the halo and it's tough to get him dry. I was so relieved to see he'd almost curled up on his blanket I'd put on the floor for him.
