My older had sensitive skin as a baby (still does to this day). She often would get a chafed, rashy bottom and nothing seemed to clear it up. A friend suggested I try making homemade baby wipes. The diaper rash went away almost immediately!
The wipes are super simple to make: mix together 2 cups water, 1 T. baby oil and 2 T. baby wash. Cut a roll of Bounty paper towels in half so that you have two short rolls. Place the paper towels in the solution and let soak. Once soaked, remove cardboard tube and voila! You have baby wipes! I stored mine in a Ziplock bag but you could also use a larger Tupperware container.
