Your health matters just as much as your baby's. If you are dealing with sore and cracked nipples, here is what you need to know.
The short answer
Sore and cracked nipples are one of the most common breastfeeding challenges, particularly in the early weeks. While mild tenderness is normal as you and your baby learn to breastfeed, significant pain, cracking, or bleeding usually indicates a latch issue that can be corrected. With proper latch technique and nipple care, most women find relief within days to a couple of weeks.
Key takeaways
- Sore and cracked nipples are one of the most common breastfeeding challenges, particularly in the early weeks. While mild tenderness is normal as you and your baby learn to breastfeed, significant pain, cracking, or bleeding usually indicates a latch issue that can be corrected. With proper latch technique and nipple care, most women find relief within days to a couple of weeks.
- Usually normal when: Mild tenderness at the beginning of a feeding during the first week that eases as the feeding continues
- Call your doctor if: You develop signs of a breast infection (mastitis) such as a red, hot, painful area on the breast along with fever and flu-like symptoms
- Varies by age — see the age-by-age breakdown below
“About 1 in 8 women experience symptoms of postpartum depression. If you have symptoms of depression that last longer than 2 weeks, tell your health care provider.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to La Leche League, ACOG, NIH guidelines, sore and cracked nipples are one of the most common breastfeeding challenges, particularly in the early weeks. While mild tenderness is normal as you and your baby learn to breastfeed, significant pain, cracking, or bleeding usually indicates a latch issue that can be corrected. With proper latch technique and nipple care, most women find relief within days to a couple of weeks. At 0-2 weeks postpartum, some nipple tenderness when your baby first latches is common during these early days as your nipples adjust to frequent nursing. However, pain that continues throughout the feeding or causes you to dread nursing is usually a sign that the latch needs adjustment. Working with a lactation consultant early can make a tremendous difference. Applying expressed breast milk or medical-grade lanolin to nipples after feeding can support healing. It is generally considered normal when mild tenderness at the beginning of a feeding during the first week that eases as the feeding continues. However, you should contact your pediatrician promptly if you develop signs of a breast infection (mastitis) such as a red, hot, painful area on the breast along with fever and flu-like symptoms.
Normal vs. Concerning
By Age
What to expect by age
0-2 weeks postpartum
Some nipple tenderness when your baby first latches is common during these early days as your nipples adjust to frequent nursing. However, pain that continues throughout the feeding or causes you to dread nursing is usually a sign that the latch needs adjustment. Working with a lactation consultant early can make a tremendous difference. Applying expressed breast milk or medical-grade lanolin to nipples after feeding can support healing.
2-6 weeks postpartum
As breastfeeding becomes more established, nipple soreness should be improving significantly. If you are still experiencing pain, cracking, or bleeding, a deeper assessment of latch, tongue tie, or other oral anatomy issues may be needed. Nipple shields can provide temporary relief while you work on the underlying cause, but they should be used under the guidance of a lactation consultant.
6-12 weeks postpartum
Persistent nipple pain at this stage is not typical and warrants investigation. Possible causes include thrush (a yeast infection that can develop on the nipples and in the baby's mouth), vasospasm (blanching of the nipples after feeding), or ongoing latch issues. Your provider or a lactation consultant can help identify and treat the specific cause.
3-6 months postpartum
New nipple soreness after a period of comfortable breastfeeding can occur when your baby begins teething or changes their feeding pattern. Biting can be addressed by briefly unlatching the baby when they bite and offering a teething toy before feeding. If you develop sudden nipple pain with white patches, thrush should be considered.
What to Tell Your Pediatrician
- Describe when you first noticed sore and cracked nipples and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if pain that persists throughout the entire feeding or gets worse rather than better over the first two weeks.
- Mention if cracks, blisters, or bleeding on the nipples that are not healing despite improved latch.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Mild tenderness at the beginning of a feeding during the first week that eases as the feeding continues
- Temporary sensitivity as your nipples adjust to the new demands of breastfeeding
- Brief discomfort when the baby first latches that resolves within the first 30 seconds of nursing
- Pain that persists throughout the entire feeding or gets worse rather than better over the first two weeks
- Cracks, blisters, or bleeding on the nipples that are not healing despite improved latch
- Nipple pain accompanied by white patches on your nipples or in your baby's mouth, which may indicate thrush
- You are avoiding or dreading feedings because of pain
- You develop signs of a breast infection (mastitis) such as a red, hot, painful area on the breast along with fever and flu-like symptoms
- A cracked nipple shows signs of infection with increasing redness, warmth, swelling, or pus
What You Can Do at Home
- Keep track of when you notice sore and cracked nipples — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that mild tenderness at the beginning of a feeding during the first week that eases as the feeding continues — this is generally within the range of normal.
- At 0-2 weeks postpartum, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Prioritize your own rest and nutrition. Accept help when offered, and do not hesitate to reach out to your healthcare provider.
- While monitoring at home, seek immediate care if you develop signs of a breast infection (mastitis) such as a red, hot, painful area on the breast along with fever and flu-like symptoms.

Related Maternal Concerns
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
Less Movement with Anterior Placenta
An anterior placenta (attached to the front wall of the uterus) acts as a cushion between the baby and your belly wall, which can make movements feel muffled or less intense. You may feel movement later (22-24 weeks instead of 18-20) and primarily on the sides and lower belly. This is normal, but you should still feel regular movement once it is established.
Placenta Position Concerns
The placenta can attach anywhere on the uterine wall - anterior (front), posterior (back), fundal (top), or lateral (sides). All positions are normal. An anterior placenta may cushion the baby's movements, making kicks feel less intense or take longer to notice. The only concern is when the placenta is low-lying or covering the cervix (placenta previa).
