There is nothing quite like the stomach-drop feeling at 2 AM when you unbutton your baby's onesie and see a bright red diaper rash. You try every cream on the shelf. You change diapers the second they get wet. Still, the rashes keep coming back again and again.

It may feel like you’re fighting a losing battle, but you are not alone. Most parents blame wetness or acidic poops, but the real culprits are usually hiding right in plain sight: constant friction and stuffy, trapped air.
