nah, be honest - you'll be a mess up until you walk him to theatre, worse for that forty minutes, then a wreck until you see him smile at you for the first time post-op - and 6 months down the track when he's happy and healthy you'll wonder what all the worry was about.

don't worry - i'm soooo the same - i was like that with DH having surgery - can't imagine what i'd be like with DD (panic merchant extraordinaire here lol)
