What Causes Nappy Rash (And How to Prevent It)
Nappy rash is one of those things almost every baby experiences at some point and while it can look uncomfortable (and feel stressful), it’s usually easy to manage once you know what’s causing it.
The key? Keeping baby skin clean, dry and protected.
The Most Common Causes of Nappy Rash
Nappy rash usually develops when:
· Moisture sits against the skin for too long
· There’s friction from a poorly fitting nappy
· Skin is irritated by urine or stool
· Wipes or products contain ingredients that don’t agree with sensitive skin
· When skin stays damp, its natural barrier weakens — making irritation much more likely.
How Nappies Can Help (Or Hinder)
A good nappy should pull moisture away from the skin, not trap it there. Highly absorbent nappies and breathable materials help keep skin drier between changes, which goes a long way in preventing rash.
If rash is a recurring issue, nappies designed for sensitive skin are often worth trying.
Choosing Baby Wipes That Are Kind to Skin
Not all wipes are created equal. For rash-prone babies, look for wipes that are:
Fragrance-free
Alcohol-free
Low in additives
Thicker wipes can also be gentler, as they clean effectively with fewer passes (less rubbing = happier skin).
Everyday Nappy Rash Prevention Tips
A few simple habits can make a big difference:
· Change nappies regularly, especially after bowel movements
· Gently pat skin dry before putting on a fresh nappy
· Use a nappy craem or barrier cream consistently, not just once rash appears
· Give baby some nappy-free time when you can
When to Get It Checked
If a rash isn’t improving after a few days, looks blistered, or seems unusually inflamed, it’s best to check in with a healthcare professional.
