To wake the baby or not wake the baby for clear liquids before surgery?!?

Brittany • Due May 30th, 2016 ❤️
My 8 month old is having surgery on Friday and  he's allowed to have clear liquids up until 5am ( and his surgery is at 9am). He sleeps through the night and usually wakes up at 6-630AM and is sooo ready for to eat in the morning. 
I was hoping some momma's with surgery experience could tell me what they did. Should I wake him up? Or just let him sleep as much as he can? 
I think I'm actually more anxious about him being hungry than the actual procedure 😩
