TKB good luck! So obviously, doh, it being the girl going in for it, it's not related to an undescended testicle.
Don't get the thing about one parent at a time, we were both allowed to go in, only DP had berd off back to work by the time he came out the other end. Actually, that was this time, with the testical op - the first time round, the time with the hernia, it was just me as he went in and just me as he came out as well.
Anyway, very good idea to give DP the going-in bit, that's much worse in my book, just feels all wrong and wierd when you see them pass out. I had dark thoughts at that point.... We were first on the list too. That's good as well. The recovery side of things is lots of cuddling and loving - normal stuff! This time round, he woke up all tearful and then went back to sleep for an hour or two, and then when he came up again the second time, the thing that really perked him up was apple juice from a BOX with a STRAW! Very exciting for him, but he was only 15 months old at the time. Anyway, it perked him up and then we could go home.
But very good luck tomorrow, take stuff for an overnight stay just in case and then of course they'll let you come home.
