I've pulled him out of formal pt for now. It's just such a yo-yo of inconsistent days - light activity the day before so that he's not overly sore the day of pt, then too sore for much activity for two days after. I'd rather he have some consistency, with certain exercises he can repeat every day and gradually increase. Hopefully he'll tolerate gym pt better in a month or two and can go back and get more benefit from it. In the meantime, we'll keep going to the Y for the pool as often as possible.
