If she wouldn't wake up, then yes. but for a bf baby, probably not.
I was in hospital just before Christmas with my newborn and the second night, she was a bit unsettled. After a few hours, finally got her to sleep and she did a poo. The midwife was there. As I was about to change her, she said let her sleep. Another midwife that came to my house checked my daughter and noticed her bum was a bit red. I said what the midwife told me. She said bf poo wouldn't cause a reaction on her bum, that the wipes would be making her go a little bit red.
