Baby skin is sensitive and changes frequently. If you are noticing head lice in baby or toddler, here is what you need to know.

The short answer

Head lice are tiny insects that live on the scalp and are spread through head-to-head contact. While uncommon in babies under 1, lice can affect toddlers, especially those in daycare. Most over-the-counter lice treatments are only approved for children 2 and older, so treating a baby or young toddler requires pediatrician guidance. Lice do not spread disease and are not a sign of poor hygiene. Manual removal with a fine-toothed nit comb is the safest approach for very young children.

What Parents Should Know

According to AAP, CDC guidelines, head lice are tiny insects that live on the scalp and are spread through head-to-head contact. While uncommon in babies under 1, lice can affect toddlers, especially those in daycare. Most over-the-counter lice treatments are only approved for children 2 and older, so treating a baby or young toddler requires pediatrician guidance. Lice do not spread disease and are not a sign of poor hygiene. Manual removal with a fine-toothed nit comb is the safest approach for very young children. At 0-12 months, head lice are rare in babies under 1 year because they have less hair and less head-to-head contact with other children. If your baby does get lice (usually from an older sibling), do not use over-the-counter lice shampoos, as they are not approved for infants. Manual removal with a fine-toothed nit comb on wet, conditioned hair is the safest method. Consult your pediatrician for guidance. It is generally considered normal when itchy scalp during the first week of treatment as lice are being removed. However, you should contact your pediatrician promptly if the scalp has become infected with redness, swelling, oozing, or pus from scratching.

By Age

What to expect by age

0-12 months

Head lice are rare in babies under 1 year because they have less hair and less head-to-head contact with other children. If your baby does get lice (usually from an older sibling), do not use over-the-counter lice shampoos, as they are not approved for infants. Manual removal with a fine-toothed nit comb on wet, conditioned hair is the safest method. Consult your pediatrician for guidance.

1-3 years

Toddlers in daycare can get head lice through head-to-head play and shared items. Look for small white or yellow eggs (nits) attached firmly to hair shafts near the scalp, and tiny moving bugs. Itching is the main symptom but may not appear for weeks after infestation. For children under 2, wet-combing with conditioner every 3-4 days for 2 weeks is the recommended first-line treatment. For children over 2, OTC permethrin products are an option. Treat all infested family members simultaneously.

What to Tell Your Pediatrician

  • Describe when you first noticed head lice in baby or toddler and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if your child under 2 has lice and you need safe treatment guidance.
  • Mention if lice have not cleared after 2 weeks of wet-combing.
  • Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
  • Bring a list of any questions or observations you want to discuss at the appointment.

What Should You Do?

When to take action

Probably normal when...
  • Itchy scalp during the first week of treatment as lice are being removed
  • Finding dead lice and old nits after treatment
  • Nits that remain attached to hair shafts for weeks after successful treatment (dead nits do not need removal but can be combed out)
Mention at your next visit when...
  • Your child under 2 has lice and you need safe treatment guidance
  • Lice have not cleared after 2 weeks of wet-combing
  • Your child has a secondary scalp infection from scratching
  • You are unsure whether what you see are lice or dandruff
Act now when...
  • The scalp has become infected with redness, swelling, oozing, or pus from scratching
  • Your baby has a fever along with an infected-looking scalp
  • You accidentally used a lice product not approved for your child's age and they are having a reaction

What You Can Do at Home

  • Keep track of when you notice head lice in baby or toddler — noting the time of day, duration, and any triggers can help your pediatrician.
  • Remember that itchy scalp during the first week of treatment as lice are being removed — this is generally within the range of normal.
  • At 0-12 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
  • Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
  • While monitoring at home, seek immediate care if the scalp has become infected with redness, swelling, oozing, or pus from scratching.

Baby Dry Scalp and Flaking - Cradle Cap

Dry, flaky skin on your baby's scalp is most likely cradle cap (infantile seborrheic dermatitis), which affects up to 70% of babies in the first 3 months. Cradle cap appears as yellow, oily, scaly patches or thick crusty buildup on the scalp. Despite its appearance, it is not painful, itchy, or contagious, and it almost always resolves on its own by 6-12 months. Treatment involves loosening the scales with oil, gentle brushing, and regular shampooing. It is not caused by poor hygiene.

Cradle Cap (Seborrheic Dermatitis)

Cradle cap is a very common, harmless condition that causes yellowish, greasy, scaly patches on your baby's scalp. It is not caused by poor hygiene, it does not bother your baby, and it almost always clears up on its own within the first several months of life.

Scabies Rash in Baby or Toddler

Scabies is a very itchy skin condition caused by tiny mites that burrow into the skin. It is common in daycare settings and spreads through prolonged skin-to-skin contact. In babies, scabies looks different than in older children - it often appears as widespread tiny bumps, blisters, and scales on the palms, soles, scalp, and face (areas not typically affected in adults). The intense itching is usually worse at night. Scabies is very treatable with prescribed medicated cream and must be treated in all household members simultaneously.

My Baby Has Impetigo

Impetigo is a common bacterial skin infection in babies and young children, caused by staph or strep bacteria. It appears as red sores that quickly develop into honey-colored crusts, most often around the nose, mouth, and hands. While it looks unpleasant, impetigo is very treatable with antibiotic ointment or oral antibiotics and clears up within a week or two of starting treatment.

My Baby Has an Extra Nipple (Accessory Nipple)

Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.

My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)

Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
