Oh Haley!!
to you.. Don't worry I know that it is very scary but he will benefit from the surgery. I know exactly how you feel when my son was 5 he had his tonsils and adneoids removed. I cried to and was so nervous for him. When he woke up in recovery I cried, the nurses looked at me like I was some weirdo, I still have a vivid memory of that day. I was so besides myself thinking back today I would have told them off.
Don't worry think of the positive side no more ear infections...
