Which cream did you apply? For my baby’s worst rash, I used Desitin Rapid Relief and it completely cleared within 3 days. During this period, make sure the bum is dry before putting on the diapers (some wet wipes are too moist, so I air dry or use tissue to dab). I also don’t wash the area too much. Again, moisture and soap is bad for healing. Hope your baby gets better soon!
