How can i relief my baby's diaper rash .. its been 2 weeks! Ive already put calmoseptine sometimes petroleum jelly. But it still there! Pls help me

Below are some tips that might help minimize diaper rash. 1. Change diapers frequently. Maybe every 4 hours depending how often the baby pee. 2. Change poopy diapers immediately. 3. Try other diaper brands. 4. Wash using a mild cleanser. 5. Try leaving the diaper off for a while, with no diaper cream on. This will help dry out the rash, which is important for the healing process.
