Boil or Abscess on Baby's Skin
The short answer
A boil (furuncle) is a painful, red, pus-filled lump caused by a bacterial infection of a hair follicle, most commonly Staphylococcus aureus. Boils in babies should always be evaluated by a pediatrician. Never squeeze or lance a boil at home, as this can worsen the infection or spread bacteria.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
Any abscess or boil in a newborn needs prompt medical evaluation. Young infants have immature immune systems and skin infections can progress quickly. A warm, red, fluctuant lump on a newborn should be seen the same day.
Boils can develop in areas of friction or moisture like the diaper area, armpits, or neck folds. Warm compresses may help bring the boil to a head, but your pediatrician should evaluate it to determine if it needs drainage or antibiotics.
As babies become more active, minor skin breaks from scratches and scrapes can allow bacteria to enter. Boils may form at these sites. Keep the area clean and covered, apply warm compresses, and see your pediatrician if the boil is larger than a pea, worsening, or your baby has a fever.
Toddlers may develop recurrent boils, especially if they carry Staphylococcus aureus on their skin. If your child gets frequent boils, your pediatrician may recommend decolonization measures such as bleach baths or nasal mupirocin ointment. MRSA (methicillin-resistant Staph) should be considered with recurrent boils.
What Should You Do?
When to take action
- A very small, superficial red bump that resolves within a day or two is likely a minor folliculitis, not a true boil
- A red, painful, growing lump develops on your baby's skin
- A boil that is not draining on its own after several days of warm compresses
- Your child has had more than one boil in the past few months
- Any boil or abscess in a baby under 3 months old
- A boil is accompanied by fever, red streaking, or rapidly spreading redness
- A boil near the eye, nose, or groin is growing quickly
- Multiple boils appear simultaneously

Related Skin Concerns
Staph Skin Infection in Baby or Toddler
Staphylococcus (staph) is a common bacteria that lives on the skin and can cause infections when it enters through a break in the skin (cut, scratch, bug bite, or eczema patch). In babies, staph infections often appear as red, swollen, warm areas that may develop pus, boils, or honey-colored crusting (impetigo). Most minor staph infections respond well to treatment. However, staph infections can spread quickly in young children and some strains (MRSA) are resistant to common antibiotics, so prompt medical evaluation is important.
Cellulitis (Spreading Skin Infection) in Baby
Cellulitis is a bacterial skin infection that causes a spreading area of redness, warmth, swelling, and pain. It occurs when bacteria enter through a break in the skin. Cellulitis in babies always requires antibiotic treatment and should be evaluated by a pediatrician promptly. If it spreads rapidly or is accompanied by fever, seek urgent care.
MRSA Skin Infection Concerns in Baby
MRSA (methicillin-resistant Staphylococcus aureus) is a type of staph bacteria resistant to common antibiotics. It can cause skin infections like boils and abscesses. While the name sounds frightening, community-acquired MRSA skin infections are treatable with appropriate antibiotics. Good hygiene and wound care are key to prevention.
Baby Acne vs Eczema: How to Tell the Difference
Baby acne and eczema can both cause facial rashes, but they look and feel different. Baby acne appears as small red or white bumps, similar to teenage acne, usually on the cheeks, nose, and forehead. Eczema causes dry, rough, red, itchy patches. Baby acne resolves on its own by 3 to 4 months, while eczema may need ongoing management.
Baby Acne (Neonatal Acne)
Baby acne is a very common, harmless condition that appears as small red or white bumps on your newborn's face, usually around 2-4 weeks of age. It is caused by maternal hormones still circulating in your baby's system and clears up on its own within a few weeks to months without any treatment.
Alopecia Areata in Babies
Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, causing round, smooth patches of hair loss. While uncommon in babies, it can occur at any age. The condition is not painful or contagious. Many children experience spontaneous hair regrowth, though it may take months. Your pediatrician or dermatologist can confirm the diagnosis.
