How do I treat and prevent diaper rash?

You can use water and washcloth or baby wipes to clean every time you change his diaper. I will make sure to clean it throughly and gently for my son then apply nappy cream for him. I find this diaper cream really good. They are sold at Watsons or Mothercare. Try to air dry before wearing back his diaper and remember to change diaper maximum 4 hours.
