Do you burp them at night? Can I skip changing them?

Do you skip burping if they're fast asleep? I keep burping and changing diaper and I think I am messing up precious nap time bc baby always passes out after feeding. I only do one boob per feed, she feeds for 10-30 minutes. Her digestion has definitely slowed down and she does a big poop around 9 am, after not pooping at night.
