It was easier in some ways than I had expected it would be (he didn't cry at all in pre op and M could go all the way to the OR with him and stayed until he was out - no tears from Will at all- I was a different story) and harder in others (he had a rough time coming out of the anesthesia - it took two doses of morphine to get him to calm down).
The procedure went as expected. The doctor feels, based on the physical findings, that we will see an improvement in his chronic sinus/ear infections, but that he probably has some sort of allergy issues. Though he tested negative for allergens in December, those results aren't reliable in kiddos under 2. So, he feels we might still have to try some other things (allergy medication, nasal steroids, etc.) in order to get him 100% healthy. That was a little disappointing, but I am glad to know that we've at least taken a major step.
Thanks for your thoughts and prayers. Now, off to baby my baby.
