So he's been breathing on his own and doing well this past day. His oxygen and blood levels look good.
He is also less sedated. Today, he actually spent a bit of time with his eyes open, getting his first good look at Kit and me. He opened his eyes briefly a few times right after he was born but has kept them basically closed since then. (I suspect he takes after me, the migrainer, and clamped his eyelids closed after getting a view of the harsh hospital lighting.)
He's definitely healing and progressing. Hopefully, within a week or so, he'll be able to come home.
