Baby skin is sensitive and changes frequently. If you are noticing toddler dry cracked lips, here is what you need to know.
The short answer
Dry, cracked lips in toddlers are common, especially during cold or dry weather. Frequent lip licking, mouth breathing, and dehydration can all contribute. Regular application of a gentle, unflavored lip balm or petroleum jelly helps protect and heal the lips. If cracking is severe or persistent, especially at the corners of the mouth, mention it to your pediatrician.
Key takeaways
- Dry, cracked lips in toddlers are common, especially during cold or dry weather. Frequent lip licking, mouth breathing, and dehydration can all contribute. Regular application of a gentle, unflavored lip balm or petroleum jelly helps protect and heal the lips. If cracking is severe or persistent, especially at the corners of the mouth, mention it to your pediatrician.
- Usually normal when: Mild lip dryness during winter or dry weather that improves with lip balm
- Call your doctor if: Lips are severely swollen, blistered, or show signs of a severe allergic reaction
- Varies by age — see the age-by-age breakdown below
“Eczema is very common in babies and children. About 1 in 10 children will develop eczema, typically starting in the first few months of life.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP guidelines, dry, cracked lips in toddlers are common, especially during cold or dry weather. Frequent lip licking, mouth breathing, and dehydration can all contribute. Regular application of a gentle, unflavored lip balm or petroleum jelly helps protect and heal the lips. If cracking is severe or persistent, especially at the corners of the mouth, mention it to your pediatrician. At 0-6 months, newborn lips may appear dry or peeling as part of the normal skin adjustment after birth. Breastfed babies sometimes develop a "nursing blister" on the upper lip, which is harmless. If lips seem persistently dry, check that baby is feeding well and hydrated (adequate wet diapers). A tiny amount of breast milk or lanolin can be applied to dry lips. It is generally considered normal when mild lip dryness during winter or dry weather that improves with lip balm. However, you should contact your pediatrician promptly if lips are severely swollen, blistered, or show signs of a severe allergic reaction.
Normal vs. Concerning
By Age
What to expect by age
0-6 months
Newborn lips may appear dry or peeling as part of the normal skin adjustment after birth. Breastfed babies sometimes develop a "nursing blister" on the upper lip, which is harmless. If lips seem persistently dry, check that baby is feeding well and hydrated (adequate wet diapers). A tiny amount of breast milk or lanolin can be applied to dry lips.
6-12 months
Increased drooling from teething can irritate the lips and surrounding skin. The cycle of moisture from drool followed by drying can cause chapping. Apply petroleum jelly to protect lips before meals and before sleep. Make sure baby is getting enough fluids through breast milk, formula, or water (for babies over 6 months).
1-2 years
Toddlers often develop a lip-licking habit that creates a cycle of drying and irritation. Flavored lip balms can actually worsen this by encouraging more licking. Use unflavored petroleum jelly or a gentle, unscented lip balm. Mouth breathing (from congestion or habit) can also dry out lips. Offer water frequently and use a humidifier in dry weather.
2-3 years
If your toddler has persistent cracking at the corners of the mouth (angular cheilitis), it could be related to drool pooling, a yeast infection, or occasionally a nutritional factor like iron or B vitamin deficiency. Mention it to your pediatrician if it does not improve with regular moisturizing. Allergic reactions to toothpaste or food can also cause lip irritation.
What to Tell Your Pediatrician
- Describe when you first noticed toddler dry cracked lips and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if cracking at the corners of the mouth that persists despite regular moisturizing.
- Mention if lips are chronically cracked, bleeding, or painful.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Mild lip dryness during winter or dry weather that improves with lip balm
- Temporary chapping from wind exposure or a cold
- Slight peeling on a newborn's lips in the first few weeks
- Brief lip dryness during a mild illness when fluid intake may be lower
- Cracking at the corners of the mouth that persists despite regular moisturizing
- Lips are chronically cracked, bleeding, or painful
- Dry lips are accompanied by signs of dehydration like fewer wet diapers, dry eyes, or lethargy
- Lips are severely swollen, blistered, or show signs of a severe allergic reaction
- Your child has signs of significant dehydration - no tears when crying, very dry mouth, sunken eyes, or markedly decreased urine output
What You Can Do at Home
- Keep track of when you notice toddler dry cracked lips — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that mild lip dryness during winter or dry weather that improves with lip balm — this is generally within the range of normal.
- At 0-6 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 lips are severely swollen, blistered, or show signs of a severe allergic reaction.

Related Skin Concerns
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.
New Treatments for Atopic Dermatitis (Eczema) in Children
Treatment for atopic dermatitis in children has advanced significantly in recent years. While moisturizers and topical steroids remain first-line treatments, newer options include non-steroidal topical medications (like crisaborole), biologic therapies (like dupilumab, approved for children 6 months and older), and JAK inhibitors. Most children's eczema is well-managed with basic skin care and mild topical treatments, but these newer options provide hope for moderate-to-severe cases.
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.
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.
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.
