Breastfeeding Problems: Common Issues and Evidence-Based Solutions (2026)

Breastfeeding is natural, but that doesn't mean it comes naturally. Most breastfeeding people encounter at least one challenge in the first weeks, and knowing what's normal, what's fixable, and when to seek help makes the difference between pushing through and giving up unnecessarily. This guide covers the most common breastfeeding problems and what the U.S. Office on Women's Health and the Academy of Breastfeeding Medicine advise for each.

Short answer: most breastfeeding pain traces back to latch, and most supply worries are not true low supply — the Office on Women's Health says most mothers make plenty of milk and that your baby's weight and growth are the best check. Get a lactation consultant involved early for pain that makes you put off feeds, and call your doctor for a breast that is hot and red with a fever, or that is not better within 24 hours.

Three companion guides cover the rest of the feeding picture: pumping at work for the back-to-work transition, our formula feeding guide for topping up or switching, and the best nursing and pumping bras for the wardrobe side of it.

Remember: Breastfeeding difficulty is not a reflection of your ability as a parent. If breastfeeding isn't working despite support, combination feeding or formula feeding are perfectly valid choices. A fed, loved baby with a healthy parent is always the goal.

Latch Difficulties

A good latch is the foundation of comfortable, effective breastfeeding — and it's the most common thing that goes wrong in the early days. Signs of a poor latch include pain throughout the feeding (not just the first 10-20 seconds), clicking or smacking sounds, baby frequently sliding off the breast, flattened or creased nipples after feeding, and baby who seems frustrated or constantly hungry.

How to improve latch: Wait for baby's mouth to open wide (like a yawn) before bringing them to the breast. Aim your nipple toward the roof of their mouth, not the center. Baby's chin should touch the breast first, with more areola visible above the upper lip than below the lower lip. Their lips should be flanged outward, not tucked in.

Tongue tie is one possible cause of a latch that will not improve with positioning. If your baby struggles to stay on the breast and you have ongoing nipple damage despite help with latch, ask your pediatrician or a lactation consultant to look at your baby's tongue movement. Whether to treat a tie is a decision for you and your baby's doctor.

A firm nursing pillow helps more than it sounds: it brings the baby up to breast height so you are not hunching to reach them, which is when a deep latch slips to a shallow one.

Painful Nursing

The Office on Women's Health puts it this way: many moms say their nipples feel tender when they first start, but breastfeeding "should feel comfortable once you and your baby have found a good latch." Pain that lasts through the feed, gets worse over time, or comes with cracking, bleeding or blistering is a sign something needs correcting — and if you find yourself putting off feedings because of pain, OWH's advice is to get help from a lactation consultant, because delaying feeds can cause more pain and harm supply.

Nipple damage most often results from a shallow latch. Correct the latch first: break the suction by placing a clean finger in the corner of your baby's mouth, then try again — your nipple should come out round, not flat or compressed. For cracked nipples, OWH suggests rubbing a few drops of expressed milk on them after feeds, using purified lanolin made for breastfeeding, and letting them air dry. Get advice from your doctor or lactation consultant before using other creams, hydrogel pads or a nipple shield. Change nursing pads often so moisture is not trapped against the skin, and skip harsh soaps — clean water is enough.

Nipple vasospasm (Raynaud's of the nipple) causes burning pain, color changes (white to blue to red), and throbbing after feeds, especially in cold environments. Keeping the breast warm after nursing and avoiding cold triggers helps many people; see your provider if it continues, because there are treatments.

Thrush (a fungal infection) has a key sign, according to OWH: sore nipples that last more than a few days even after your baby has a good latch, or soreness that starts suddenly after weeks of pain-free feeding. Nipples may look pink, flaky, shiny, itchy or cracked, and you may have shooting pains deep in the breast during or after feeds. It can pass between your baby's mouth and your nipples, so call both your doctor and your baby's doctor.

Low Milk Supply

"Most mothers make plenty of milk for their babies," the Office on Women's Health says, "but many mothers worry about having enough." Two normal changes set off most of that worry. Around six weeks to two months your breasts may no longer feel full, and your baby may nurse for only five minutes at a time — OWH calls that you and your baby getting good at it. And growth spurts, which often happen around 2 to 3 weeks, 6 weeks and 3 months, make babies nurse longer and more often for a few days.

How to tell if your baby is getting enough: OWH's answer is that checking your baby's weight and growth is the best way, so keep the early pediatrician weight checks and tell your baby's doctor if you are concerned.

If supply needs a boost, OWH recommends: make sure your baby is latched and positioned well; breastfeed often and let your baby decide when to end the feeding; offer both breasts at each feeding, keeping your baby on the first side as long as they are still sucking and swallowing; and avoid giving formula or cereal in addition to breast milk unless your baby's doctor advises it, because your baby may lose interest and your supply will fall. If those steps do not help, see your doctor to check for health issues such as hormonal problems. If you do need to add formula, our combination feeding guide explains how to protect the supply you have.

Lactation cookies, teas and supplements are popular, but none of them replaces frequent, effective milk removal. Talk to your provider before taking any herbal supplement while breastfeeding.

Oversupply and Fast Letdown

Too much milk brings its own set of problems: baby choking or sputtering during feeds, excessive spitting up, gassiness, green frothy stools, and the parent experiencing painful engorgement and frequent leaking.

One side per feeding is OWH's first step for oversupply: breastfeed on one side for each feeding and keep offering that same breast for at least two hours, until the next full feeding. If the other breast becomes unbearably full, hand express for a few moments to relieve the pressure, and use a cold compress for discomfort. Feed before your baby is overly hungry to prevent aggressive sucking, and burp often. Work with a lactation consultant if you are reducing supply on purpose. Nursing pads handle the leaking in the meantime — change them often.

For a strong let-down: OWH suggests holding the nipple between your first and middle fingers and pressing lightly to slow the flow; unlatching if your baby chokes or sputters and letting the extra milk spray into a towel; and trying positions that reduce the force of gravity, such as side-lying or the football hold.

Engorgement

Some fullness is normal when milk comes in. Engorgement is when breasts feel very hard and painful; OWH says it usually happens during the third to fifth day after giving birth but can happen any time milk is not removed often enough. It can bring swelling, tenderness, warmth, redness, throbbing, a flattened nipple and a low-grade fever, and it can lead to plugged ducts or infection, so it is worth heading off.

What helps: breastfeed often and let your baby feed as long as they like while latched well; hand express or pump a little to soften the areola before a feed so your baby can latch; try reverse pressure softening (pressing inward around the base of the nipple for a slow count of 50); use cold compresses between feedings; and wear a well-fitting, supportive bra that is not too tight. Ask your doctor which pain reliever is right for you.

Blocked Ducts and Mastitis

A plugged duct feels like a tender, sore lump in one breast, without fever. Mastitis adds systemic symptoms — OWH lists fever or flu-like aches, nausea, and a breast that feels warm or hot and looks pink or red. The two can be hard to tell apart early on, and both often improve within 24 to 48 hours.

The advice here has changed, and you will hear both versions. Older guidance, still on many handouts, recommends warm compresses and firm massage toward the nipple. The Academy of Breastfeeding Medicine's 2022 mastitis protocol reversed much of that. It says to "feed the infant on demand, and do not aim to 'empty' breasts"; to "avoid deep massage of the lactating breast," because deep massage increases inflammation and tissue swelling; to minimize breast pump use; to wear an appropriately fitting supportive bra; and to use ice and anti-inflammatory medication to reduce swelling and pain. It also explains that a single duct cannot literally be blocked by a "plug" of milk — the lump is narrowed, inflamed tissue, which is why gentleness works better than force. Ask your own provider or lactation consultant which approach they want you to follow, and about medication doses.

When to call the doctor: OWH says to ask for help if you do not feel better within 24 hours, if you have a fever, or if symptoms get worse — you might need medicine. See your doctor right away if both breasts look affected, there is pus or blood in your milk, you see red streaks near the sore area, or symptoms came on severely and suddenly. Rest matters too: OWH notes that a breast infection is often a sign you are doing too much.

When to See a Lactation Consultant

An International Board Certified Lactation Consultant (IBCLC) holds the most rigorous credential in breastfeeding support. See one if pain persists beyond the first two weeks, your baby isn't gaining weight adequately, you suspect tongue tie, you're struggling with latch despite trying positioning adjustments, you have recurrent blocked ducts or mastitis, or you want help transitioning from pumping to direct breastfeeding.

Many IBCLCs offer home visits (where they can observe a full feeding) and virtual consultations. HealthCare.gov states that health insurance plans must provide breastfeeding support, counseling and equipment (grandfathered plans excepted) — call your insurer for in-network consultants. Hospital lactation consultants are available during your postpartum stay, but don't hesitate to seek help after discharge, when the real challenges often emerge.
