Not this type of hernia I don't think, but DS1 had a double hernia operation at 3 months old, they were getting bigger and bigger and really bulging, so he was done quickly, they never mentioned anything about the sick thing? And he can be sick now.
DS1 is now 7 and you can't see any scaring at all, he was fine on the day itself, the no milk thing really worried me as he was a big baby, but he managed on water sips before the operation, sone at 9am after getting to the hospital at 7am, Chelsea and Westminster London. Handing him over was the worst part, you will probably be able to stay while they put him under as he is older. DH had to do it and I was so worried the whole time, the second they said it had all gone well and I could go and get him was brilliant. He gulped down some milk and looked happy!
We just had to wait for him to wee then we went home. They put glue instead of stitches and covered both wounds with a massive peice of clear plastic that was like a second skin. It did not bother him at all!
The staff we just fantastic, really caring and understanding of that fact you are wobbly and worried, lots of TLC and tissues.
Write your questions down, can you email/send a letter, when is your next appt? Do you have one before the surgery? The more you know the better prepared you will feel to deal with the day.
Good luck, it will be fine. x
