Baby Skin Infections: How to Spot Them and What to Do

Worried about a red spot or sore on your baby’s skin? You’re not alone. Babies get skin infections often because their skin is thin and their immune systems are still learning. Knowing the common types, quick home steps, and warning signs makes a big difference.

Common infections and how they look

Impetigo: This bacterial infection often shows as red sores that burst and form yellow-brown crusts, usually around the nose and mouth. It can spread quickly if untreated.

Yeast (Candida) infections: These are common in diaper areas and skin folds. The skin looks bright red, may have small bumps at the edges, and often won’t improve with regular diaper rash creams.

Cellulitis: A deeper bacterial infection that makes skin swollen, warm, and very red. Babies may also have fever or act more sleepy than usual. This needs fast medical care.

Viral rashes: Viruses can cause spotty rashes that come with fever or cough. They’re often widespread and may fade as the illness passes.

Practical home care and easy prevention

Keep the area clean: Gently wash affected skin with warm water and a mild soap. Pat dry—don’t rub. Moisture traps germs, so dry skin matters.

Diaper-area tips: Change diapers often, use a breathable barrier like petroleum or zinc oxide after cleaning, and let the baby go diaper-free for short periods. If the rash looks bright red with little bumps along the edge, it’s likely yeast—an antifungal cream from your pharmacist or doctor usually helps.

Don’t pick or squeeze crusts: For impetigo, avoid touching crusts; that spreads bacteria. Clean crusts with warm water and cover if needed. Your doctor may prescribe a topical antibiotic (like mupirocin) or an oral antibiotic if it’s widespread.

Avoid sharing towels and clothes: Wash cloths, bedding, and soft toys in hot water when your baby has a contagious skin infection. This cuts the chance of reinfection.

When to call the pediatrician: Get help if the baby has a fever, if redness spreads quickly, if the baby seems very uncomfortable or less responsive, if the rash develops pus, or if home care doesn’t help in 48 hours. Also call if the rash is near the eyes, mouth, or genitals.

Small steps at home can stop many problems from getting worse, but trust your instincts. If something looks painful, angry, or different from usual, a quick call to your doctor avoids bigger trouble later.
