Highschool graduation with newborn?

So I graduate May 20th, graduation rehearsal is May 17th and my due date is May 8th 🤷🏻‍♀️ he'll only be a week old for the rehearsal and not even two weeks old during graduation. I know I won't be comfortable leaving him alone that early but I also don't want to miss this big day seeing as I did it for him. So does anyone have any suggestion cause they won't give you the tickets if you don't show up to the rehearsal, and I already paid for my cap and gown. I could talk to them but I'm worried they'll tell me not to bother coming for either one.
