circumcision

okay so my son is 1 1/2 years old and today he had an appointment bc his foreskin won't go back (which I think is his doctors fault bc she told me not to pull it back til he was a year and I thought she knew what she was talking about and this was my first child so I just took her advice and didn't touch it) and now in January he has to be circumsized bc it isn't able to be pulled back and I'm not really scared about the surgery itself but more about the fact that he has to be put to sleep and from the horror stories I've heard of toddlers being put to sleep I'm very worried.. Has anyone had this done on a toddler or had their toddler put to sleep? I really need to calm myself down.. thank you..
