Could really use some positive vibes

Tomorrow my toddler is having dental surgery. I’m a nervous wreck. I don’t want to see him under anesthesia again. It was absolutely heartbreaking last time. And he can’t eat or drink anything after 6AM. He likes to wake up at 7 and eat at 8 and then have lunch around 11. Well his appointment isn’t until 12:45 so I’m stressing about how the hell im just supposed to tell him “no you can’t eat” all morning. He’s going to be so hungry :(
