💩💩💩POOP! That’s right, poop. Urine does NOT cause diaper rash, but stool is the culprit for skin breakdown leading to rash. So poopy diapers that sit too long may cause a diaper rash, but more likely there is another root cause. That being said, never let a dirty diaper go for too long. How does poop cause a rash? Changes in the gastrointestinal (GI) tract can cause the acidity of poop to change. This can be anything from a common cold virus, antibiotics (especially Augmentin), or a change/transition to formula. The acidity against the skin causes the first layers of the skin to breakdown, leading to a rash, irritated, red skin, and sometimes even open sores. How do I prevent a diaper rash? There’s no need to apply diaper cream at every diaper change unless you start seeing redness. If you want, you can apply something such as coconut oil or Aquaphor, but it’s not necessary. I actually don’t apply anything unless I am starting to see redness. This is more effective than a diaper rash remedy! See blog post for full remedy LTKfamily LTKbaby LTKbump
