📋 TL;DR
- A good latch should not cause sustained pain
- Signs of a poor latch include clicking sounds, creased nipples, and shallow sucking
- Tongue-tie and lip-tie are common correctable causes of latch problems
- A lactation consultant can resolve most latch issues in one or two sessions
👩♃️ Doctor’s Take
“Pain during breastfeeding is not a badge of honor. Many mothers are told it’s supposed to hurt, but that’s incorrect. Brief discomfort during the first five to ten seconds of latch can be normal in the first week, but sustained pinching, cracking, or bleeding indicates a problem. Fixing the latch makes breastfeeding comfortable and effective.” — Dr. Zoya Arshad, MD, FAAP
What a Good Latch Looks Like
A good latch is the foundation of successful breastfeeding. When your baby latches correctly, their mouth covers not just the nipple but a large portion of the areola, with the nipple pointing toward the back of the soft palate. The baby’s lips are flanged outward like fish lips, the chin is pressed into the breast, and the nose is slightly away from the breast to allow breathing. You should hear and see rhythmic sucking and swallowing, with brief pauses between bursts of sucking. The latch should feel comfortable after the initial five to ten seconds of latch-on.
Signs of a Poor Latch
Knowing the signs of a poor latch helps you correct it early. Common indicators include sustained pain throughout the feed, a creased or flattened nipple when it emerges from baby’s mouth (it should be round), clicking or smacking sounds during feeding, shallow sucking with rapid motion rather than deep rhythmic draws, baby’s lips tucked inward rather than flanged outward, and baby sliding off the breast repeatedly. Nipple cracking, bleeding, or blistering after feeds is a clear sign of poor latch mechanics.
Common Causes of Latch Problems
Tongue-tie (ankyloglossia): A tight frenulum restricts the tongue’s mobility, making it difficult for baby to lift the tongue to the palate and create the wave-like motion needed to extract milk. Signs include heart-shaped tongue tip, inability to stick out the tongue past the gumline, and clicking during feeds.
Lip-tie: A tight upper lip frenulum prevents the upper lip from flanging outward, breaking the seal needed for effective sucking. This often accompanies tongue-tie.
Recessed chin or high palate: Anatomical variations can make it harder for baby to achieve a deep latch. These are usually identified by a lactation consultant or pediatrician.
Engorgement: When breasts are overfull, the areola becomes firm, making it difficult for baby to compress the milk ducts. Reverse pressure softening or expressing a small amount before latching can help.
How to Improve the Latch
Start by positioning your baby correctly. The baby should face the breast directly, tummy to tummy, without needing to turn their head. Their nose should align with your nipple. Wait for a wide-open mouth like a yawn before bringing baby to the breast, not the breast to the baby. Aim the nipple toward the roof of baby’s mouth, and ensure the chin touches the breast first with the nose clear. If the latch is painful, break the suction by inserting your pinky finger into the corner of baby’s mouth and try again.
When to See a Lactation Consultant
An International Board Certified Lactation Consultant (IBCLC) can assess latch, identify anatomical issues like tongue-tie, and create a feeding plan. Most latch issues resolve with one or two sessions. Your pediatrician can provide a referral, and many insurance plans cover lactation consultation. If you have persistent pain, recurrent mastitis, or your baby is not gaining weight adequately, see a specialist promptly.
Nipple Pain: What Is Normal and What Is Not
Brief tenderness during the first few seconds of latch can be normal as the nipple stretches into position. This should subside within ten seconds and not return until the next feed. Sustained pain lasting throughout the feed, pinching or burning sensations, visible damage like cracks or blisters, or pain that persists between feeds is not normal and indicates a correctable problem. Nipple shields should be used only under professional guidance as they can reduce milk transfer.
The Role of Nipple Shapes and Anatomy
Flat or inverted nipples can make latching more challenging but not impossible. Many women with flat nipples breastfeed successfully with proper positioning. Techniques that help include using a breast pump for thirty to sixty seconds before latching to draw out the nipple, using nipple everting devices, or trying different positions like the football hold. Nipple shells worn between feeds can help draw out flat nipples gradually.
