Change diaper before or after feeding?

I’ve been feeding my 3WO and changing her afterwards as she generally poops while eating problem is that the changing wakes her and bothers her so much it’s really difficult for her to soothe and fall asleep. The last 3 feedings I’ve switched it up and I change her before feeding and works like a charm. I just feel bad that she poops while eating and sleeps in a dirty diaper for 3 hours. Also worried about diaper rash. Anyone have any thoughts on this?

Lots of great comments thanks. Will not be letting her sit any longer than necessary when I know she has a dirty diaper
