Is it normal for a baby to always have a diaper rash?

Despite frequent changes, diaper rash may persist due to prolonged moisture exposure, friction, or sensitivity to diaper materials. Skin pH imbalance and microbial overgrowth—especially Candida—can also lead to recurrent rashes, emphasizing the need for proper skin barrier support and tailored hygiene practices. If it doesn't clear in days, see a paediatrician—it could be fungal or allergic.
