Baby is 8 weeks. Do you change diaper during night?

We are kind of to the point of sleeping longer stretches. He is EBF so we roll over and feed every time he wakes up (we cosleep) then fall right back asleep. No burping or diaper changes unless I smell poop. Is that wrong? It doesn't bother him. Not that I left him sit in pee/poop but he isn't really awake long to do either. So how long do you go at night??
