Baby skin is sensitive and changes frequently. If you are noticing dry, cracked lips in newborns, here is what you need to know.
The short answer
Dry, peeling, or cracked lips in newborns are very common and usually harmless. They can result from the transition to a drier environment outside the womb, frequent sucking during feeding, or mild dehydration. Applying a small amount of breast milk or lanolin to the lips can help. Persistent dryness with other symptoms like decreased wet diapers may indicate dehydration.
Key takeaways

They can result from the transition to a drier environment outside the womb, frequent sucking during feeding, or mild dehydration. Applying a small amount of breast milk or lanolin to the lips can help. Persistent dryness with other symptoms like decreased wet diapers may indicate dehydration.
- Usually normal when: Mild peeling or dryness of the lips in the first few weeks of life
- Call your doctor if: Severely cracked lips along with decreased wet diapers, sunken fontanelle, or lethargy, which could indicate dehydration
- 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.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, Mayo Clinic guidelines, dry, peeling, or cracked lips in newborns are very common and usually harmless. They can result from the transition to a drier environment outside the womb, frequent sucking during feeding, or mild dehydration. Applying a small amount of breast milk or lanolin to the lips can help. Persistent dryness with other symptoms like decreased wet diapers may indicate dehydration. At 0-1 month, newborns often develop dry or peeling lips as their skin adjusts to life outside the womb. Frequent sucking during breastfeeding or bottle-feeding can also cause the lip skin to peel or develop a callus-like blister (sucking blister), which is harmless. You can apply a small amount of breast milk, lanolin, or a gentle lip balm to help moisturize. Avoid lip balms with fragrances, dyes, or potential allergens. Ensure your baby is feeding well and producing adequate wet diapers. It is generally considered normal when mild peeling or dryness of the lips in the first few weeks of life. However, you should contact your pediatrician promptly if severely cracked lips along with decreased wet diapers, sunken fontanelle, or lethargy, which could indicate dehydration.
Normal vs. Concerning
By Age
What to expect by age
0-1 month
Newborns often develop dry or peeling lips as their skin adjusts to life outside the womb. Frequent sucking during breastfeeding or bottle-feeding can also cause the lip skin to peel or develop a callus-like blister (sucking blister), which is harmless. You can apply a small amount of breast milk, lanolin, or a gentle lip balm to help moisturize. Avoid lip balms with fragrances, dyes, or potential allergens. Ensure your baby is feeding well and producing adequate wet diapers.
1-3 months
Lip dryness and peeling from sucking may continue but is typically harmless. A sucking callus or blister on the upper lip is common in breastfed babies and resolves on its own. If lips appear very dry, cracked, or bleeding, ensure your baby is well-hydrated by monitoring wet diapers and feeding frequency.
3-6 months
Lip dryness related to the newborn period should have resolved. Persistent dry, cracked lips may be related to environmental factors (dry air, wind) or could be an early sign of eczema around the mouth. Use a gentle moisturizer and consider a humidifier if the air is dry.
6-12 months
Dry lips at this age may be related to drooling, teething, or environmental factors. As babies start solid foods, food irritation around the mouth can also cause dryness and redness. Applying a barrier cream before meals can help protect the skin.

- Mention if dry lips accompanied by dry skin elsewhere on the body.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.

What You Can Do at Home
- Keep track of when you notice dry, cracked lips in newborns — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that mild peeling or dryness of the lips in the first few weeks of life — this is generally within the range of normal.

Normal Skin Peeling After Birth
Skin peeling in newborns is very normal, especially in the first one to three weeks after birth. Babies who were born past their due date often have more peeling. The peeling happens as the skin adjusts from the watery environment of the womb to the drier outside air. No treatment is needed, and the peeling will resolve on its own.
Sucking Blisters on Lips and Hands
Sucking blisters or calluses are common, harmless skin changes caused by the friction of breastfeeding or bottle-feeding. They appear as a thickened, sometimes whitish or blister-like area on the center of the upper lip. Some babies are even born with sucking blisters on their hands or wrists from sucking in the womb. They resolve on their own and do not need treatment.
How Many Wet Diapers Are Enough
In the first few days, expect at least one wet diaper per day of life (1 on day 1, 2 on day 2, etc.). By day 4-5, your baby should have at least 6 wet diapers per day. This is one of the best indicators that your baby is getting enough milk. Modern diapers are very absorbent, so check by feeling the weight of the diaper.

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.
