Hello everyone. Girls, how do you treat diaper rash on your daughter's bottom? Sudocrem and Bepanthen aren't helping, we've been suffering for over a week. It all started because we bought Huggies Ultra Comfort diapers for boys, although we used to buy them for girls, but since there were no girls' diapers left in the store, and I was rushing somewhere and didn't have time to go to another store. Now we're back to our diapers, but the diaper rash still hasn't gone away.
