Do you wipe baby every time you change their diaper even if they only peed?

I’m having a debate with my mother because she doesn’t think it’s necessary if they just peed so she just puts on a new diaper.

I think that not wiping when the pee could lead to a rash.

And yes I know, my baby, my rules and she will if I ask her to. I’m just trying to see what the norm is.
