So here's how it all worked out.
I called my lactation consultant. She contacted a friend of hers who is a surgical nurse and they said that breastmilk is supposed to be considered a clear fluid. She recommended that I feed him about three hours ahead of time, so that he'd be getting hungry right as he went under.
So I fed him at 10am. We drove over to Children's with my mom (his grandma). The anesthesiologist had a horrible bedside manner in general, but he wasn't very happy with me, because apparently it is *hospital policy* not to consider BM a clear fluid. So they moved another child in front of my son in the queue and then took him. He got a bit hungry, but my mom rocked him - I tried to stay away so that my bb's didn't drive him nuts. They ended up taking him at 1:30, which was earlier than the *hospital policy*.
I am a rules person and I don't like not following instructions. But I am glad that I did it this way. Even if we had to wait longer than we did, I would rather have him hungry at the very end, right before they come to take him, then risk having him be ravenous on the drive across town and be kept waiting for potentially even longer.
In recovery, the nurse initially offered pedialyte, but when I said he was EBF, she was like, oh forget about it. BM is all he needs!
Thanks for the input.
