Iyyar did great in surgery and afterward. He set some kind of popsicle-eating record, such that the nurse who initially said "no such thing as too many fluids, just keep bringing them on" finally called a popsicle time-out at around 8:30 pm after the seventeenth popsicle (and that's not counting the Italian ices, or the juice). He spend the afternoon zoned out in front of Sesame Street with the popsicles; the only thing that really seemed to be bothering him was the IV and the ID tag, which he cried about every time he noticed them.
I came home an hour ago and Abba is at the hospital now, which I'm starting to feel was a mistake; I called a little while ago and heard a lot of howling. It's not that Iyyar needs me more or is more attached to me (not at all, in fact) but he doesn't settle as well with Abba, who he knows is, well, more or less wrapped around his little finger.
If all continues to go well he'll be discharged in the morning. Right now the main issue is seeing how he breathes when he's asleep. Here's hoping that all goes well, and he'll be eating his popsicles at home.
