You are lucky. My 3.5 and 2-year-old have woken me up to go potty at least one time every night for the past year. It is usually around 2-3 am and I'm lucky if they let me sleep in past 6 am because they want breakfast. I'm starting to wonder if I'll ever get a full nights rest again
I have no advice for you, but I will be watching this thread for ideas!
