A baby girl should be wiped after changing a pee diaper.
With a baby girl they can get Urinary Tract Infections more easily from the bacteria from the urine that can get into the baby girls vagina.
So it's best to wipe the pee off the baby girl when you change their diaper.
Even using a wet wash cloth to wipe pee from your baby girl or even baby boy is good either way because the urine can cause a rash.
I've always wiped my babies skin even with a wet wash cloth when changing a pee diaper as their skin has sometimes had a little bit of pee on it.
It also makes the kid or baby feel fresher and cleaner when you put the new diaper on them and it prevents the urine from becoming stale on their skin and smelling.
