Introduction
Breastfeeding is often described as the most natural thing in the world. While it is a natural biological process, it is also a learned skill for both you and your baby. Many new parents feel a mix of excitement and anxiety during those first few days, wondering if their little one is actually getting enough milk. The key to a successful breastfeeding journey often starts with one specific thing: the latch. A latch is simply how your baby attaches their mouth to your breast.
At Milky Mama, we believe that every drop counts and that you deserve to feel empowered throughout this process. Our founder, Krystal Duhaney, RN, BSN, IBCLC, created this community to provide the clinical expertise and compassionate support families need to thrive. Whether you are navigating your first few feeds or looking to improve a painful experience, understanding the mechanics of a good latch is essential. If you want a more structured foundation, our Breastfeeding 101 course can help you build confidence as you learn the basics.
This guide will help you identify the physical, visual, and audible signs of a deep latch so you can breastfeed with confidence and comfort.
Why a Good Latch Matters
The quality of the latch determines how effectively your baby can remove milk from the breast. When a baby has a deep, effective latch, they can access the milk easily, which keeps them satisfied and helps them grow. Beyond just feeding the baby, the latch plays a critical role in your physical well-being.
Protecting Your Milk Supply
Breastfeeding works on a "supply and demand" basis. This means your body produces milk based on how much is removed. If the latch is shallow, the baby may not be able to drain the breast effectively. Over time, this can signal your body to slow down production because it thinks the milk is not needed. A deep latch ensures your breasts receive the proper stimulation to maintain a robust supply for your baby’s needs. If you’re wondering whether supply may actually be the issue, our Understanding and Managing Low Milk Supply guide breaks down the warning signs and next steps.
Preventing Nipple Pain and Damage
One of the most common myths in breastfeeding is that it is supposed to hurt. While some initial tenderness or "learning curve" sensitivity is normal in the first week, breastfeeding should not be a painful experience. A shallow latch—where the baby is only sucking on the tip of the nipple—is usually the culprit behind cracked, bleeding, or blistered nipples. A deep latch protects your delicate tissue by positioning the nipple far back in the baby's mouth, where the palate is soft and does not cause friction. If you need a step-by-step refresher, the 5 Steps To Get The Perfect Latch guide walks through the basics.
Preventing Clogs and Mastitis
When milk is not moved effectively out of the breast, it can back up in the milk ducts. This can lead to uncomfortable lumps known as plugged ducts. If these plugs are not resolved, they can sometimes lead to mastitis, which is an infection of the breast tissue that often causes flu-like symptoms. Ensuring a good latch from the start is one of the best ways to keep milk flowing and your breasts healthy.
What a Good Latch Feels Like
The way breastfeeding feels is often the most reliable indicator of a good latch. Because you cannot always see exactly what is happening inside your baby’s mouth, you have to rely on your physical sensations.
The Difference Between Tugging and Pinching
A good latch should feel like a firm, rhythmic tugging sensation. It might feel strong, but it should not feel sharp. You should feel a "pull" as the baby uses their tongue and jaw to draw milk out. If you feel a pinching, biting, or "paper cut" sensation, the latch is likely too shallow. This usually means the nipple is being pressed against the baby’s hard palate (the roof of the mouth) rather than resting against the soft palate in the back.
The Initial "Latching On" Sensation
When your baby first attaches, you might feel a brief moment of intense sensation. This is often the nipple stretching to accommodate the latch. However, this feeling should fade within a few seconds as the baby settles into a rhythm. If the pain persists throughout the entire feeding, it is a sign that you should unlatch and try again.
Relaxation and Comfort
Once the baby is latched deeply and the milk begins to flow, you should ideally feel a sense of relaxation. For many, the "let-down reflex"—which is the process of milk moving forward through the ducts—can cause a tingling or pins-and-needles sensation. This is normal and a great sign that the baby is successfully stimulating the breast.
Key Takeaway: If it hurts, something is likely wrong. Don't "tough it out." A small adjustment to the latch can make a world of difference for your comfort and your baby's nutrition.
Visual Signs of a Good Latch
While sensations are vital, looking at the positioning of the baby’s mouth and body can provide clear clues about the quality of the latch.
The Wide Open Mouth
Before the baby latches, they should open their mouth very wide—like a big yawn. A common mistake is letting the baby latch when their mouth is only partially open. A wide mouth allows the baby to take in a large "mouthful" of breast tissue, not just the nipple.
Flanged "Fish Lips"
Look at your baby’s lips once they are attached. Both the top and bottom lips should be "flanged" or turned outward. They should look like fish lips. If the lips are tucked in (inverted), the baby is likely gripping the nipple too tightly with their gums. You can sometimes gently use your finger to flip a tucked lip outward without breaking the latch.
Asymmetrical Latch
A perfect latch is usually "asymmetrical." This means the baby covers more of the areola (the dark circle around the nipple) with their bottom lip than their top lip. You should see more areola visible above the baby’s top lip than below their bottom lip. This position ensures the nipple is aimed toward the roof of the baby's mouth, providing the deepest possible attachment.
Chin and Nose Position
In a good latch, the baby’s chin should be buried firmly into the breast. This pressure helps stimulate the milk ducts. The nose, however, should be clear or only lightly touching the breast. Many parents worry about the baby being able to breathe, but babies have "flared" nostrils designed to allow air in even when their face is close to the breast. If their nose seems too buried, try bringing their bottom closer to your body to tilt their head back slightly.
Rounded Cheeks
Your baby’s cheeks should look full and rounded while they are nursing. If you see dimples or "caves" in their cheeks as they suck, it may mean they are breaking the seal or using too much suction to compensate for a shallow latch. Rounded cheeks indicate that the baby has a solid, airtight seal around the breast.
Audible Signs and Swallowing Patterns
What you hear is just as important as what you see. Monitoring the sounds and rhythms of a feed can tell you if the baby is actually getting milk.
Sucking vs. Swallowing
In the beginning of a feed, the baby will usually take short, fast sucks to trigger the milk to flow. Once the milk "lets down," the rhythm should change to a deep, slow "suck-swallow-breathe" pattern. You should be able to see a visible movement in the baby’s jaw that extends all the way back to their ear.
The Sound of Success
A quiet "ca" or "glug" sound is the hallmark of a good swallow. You might not hear it every single time, especially if your milk flow is slower at that moment, but you should hear it frequently throughout the feed. If you hear clicking or smacking sounds, it usually means the baby is losing the suction seal. Clicking often happens when the latch is shallow or if the baby has a tongue-tie that prevents them from holding the breast securely.
The "Satiety" Pause
As the baby gets full, they will naturally slow down. You might notice longer pauses between swallows. This is normal. A baby who is well-latched and getting plenty of milk will eventually release the breast on their own, looking "milk drunk"—relaxed, sleepy, and with open, floppy hands.
How to Achieve a Deep Latch: Step-by-Step
Getting a good latch often requires a bit of "prep work." Following these steps can help set you and your baby up for success at every feeding.
- Get Comfortable First: Use pillows to support your back and arms. You should not have to lean forward to reach the baby; instead, bring the baby to your breast.
- Align the Baby: Hold the baby so their ear, shoulder, and hip are in a straight line. They should be "tummy-to-tummy" with you so they don't have to turn their head to reach the nipple.
- Nipple-to-Nose: Instead of pointing your nipple at the baby’s mouth, point it at their nose. This encourages them to tilt their head back, which helps them open their mouth wider.
- The "Sandwich" Hold: Use your hand to gently compress your breast tissue behind the areola. Think of it like squishing a large sandwich so it fits into a mouth. Your fingers should be well back from the nipple so they don't get in the baby's way.
- Tickle and Wait: Gently tickle the baby’s lips with your nipple. Wait for that big "yawn" opening.
- The "Scoop": When the mouth is wide, quickly but gently bring the baby onto the breast, aiming their lower jaw well below the nipple.
The Role of Positioning
Sometimes, a latch isn't working simply because of the angle. Experimenting with different positions can help you find what works best for your body and your baby's current size.
Laid-Back Breastfeeding (Biological Nurturing)
This is one of the most effective positions for newborns. You recline back at a 45-degree angle and let the baby lie on their tummy directly on top of you. Gravity helps the baby’s body mold to yours, and their natural instincts often lead them to a deep, comfortable latch without much "prodding."
The Cross-Cradle Hold
This position gives you a lot of control. You hold the baby with the arm opposite the breast you are using. Your hand supports the base of the baby’s head and neck, allowing you to guide them onto the breast precisely. This is often the "go-to" for parents learning to latch for the first time.
The Football Hold
The baby is tucked under your arm like a football, with their feet pointing toward your back. This is an excellent choice for those who have had a C-section (as it keeps the baby off the incision) or for those with larger breasts.
Side-Lying Position
Once you and the baby have the hang of things, side-lying is a wonderful way to rest while feeding. You both lie on your sides facing each other. This is particularly helpful for middle-of-the-night sessions, though you must ensure a safe sleep environment.
Troubleshooting a Shallow Latch
Even with the best intentions, a latch can sometimes slip or start off shallow. Knowing how to fix it is a vital skill.
Breaking the Suction
If the latch hurts or you see signs of a shallow attachment, do not just pull the baby off. This can cause significant nipple damage. Instead, gently slide a clean finger into the corner of the baby’s mouth to break the suction seal. Once the seal is broken, you can safely remove the baby and try again.
Skin-to-Skin Contact
If you or the baby are getting frustrated, take a break. Strip the baby down to their diaper and place them directly on your bare chest. This skin-to-skin contact helps regulate the baby’s temperature and heart rate and triggers their feeding instincts. It also helps calm your nervous system, which is essential for the let-down reflex.
Calming the Baby First
It is very difficult to get a good latch on a baby who is already screaming or "frantic." If the baby has missed their early hunger cues and is now upset, try to calm them before attempting to latch. You might try a few minutes of rocking, shushing, or letting them suck on a clean finger to reset their focus. If you still need personalized support, our Certified Lactation Consultant Breastfeeding Help page can connect you with expert guidance.
Supporting Your Journey
While mastering the latch is a physical skill, your overall wellness plays a huge role in your breastfeeding experience. Hydration and nutrition are the foundations of lactation. We often suggest incorporating supportive snacks and drinks into your routine to keep your energy up.
For example, our Pumpin’ Punch™ is a great way to stay hydrated while enjoying ingredients that support nursing parents.
If you're looking for a convenient snack, our Emergency Lactation Brownies are a favorite among our community. They are packed with oats, brewer's yeast, and flaxseed—ingredients traditionally used as galactagogues (foods that may help support milk supply).
Supplements and Herbs
Many moms find that herbal support can help bridge the gap if they are worried about their supply. Products like our Pumping Queen™ are designed to support lactation through traditional herbal blends. It is always important to remember that every body is different, and what works for one person may vary for another.

What to Do Next: A Checklist for Success
If you're currently struggling or just starting out, use this quick checklist to evaluate your next feeding session:
- Check your pain level: Is it a 0 or 1 out of 10? If it's higher, break the seal and relatch.
- Observe the lips: Are they flanged out like a fish?
- Listen for swallows: Do you hear a rhythmic "ca" sound after the first minute?
- Monitor the chin: Is it pressed firmly into the breast tissue?
- Check the nipple shape: When the baby unlatches, does your nipple look round and elongated? (It should not look like a new tube of lipstick or be flattened on one side).
If you want another easy hydration option, Lactation LeMOOnade™ is another simple addition to explore.
When to Call a Lactation Consultant
You don't have to do this alone. While articles and videos are helpful, nothing replaces the hands-on (or virtual) eyes of a professional. Consider reaching out to an International Board Certified Lactation Consultant (IBCLC) if:
- Breastfeeding remains painful after the first minute of every feed.
- Your nipples are cracked, bleeding, or consistently misshapen after nursing.
- Your baby is not meeting their expected number of wet and dirty diapers.
- The baby seems constantly frustrated at the breast or refuses to latch.
- You are concerned about your baby's weight gain.
An IBCLC can check for things like a tongue-tie or lip-tie, which can make a good latch physically impossible for a baby regardless of your technique. They can also help you find the specific positions that work for your unique anatomy.
Summary of a Good Latch
Achieving a good latch is the cornerstone of a healthy breastfeeding relationship. It ensures your baby is well-fed, your milk supply is protected, and your body is comfortable. By focusing on a wide-open mouth, flanged lips, and an asymmetrical attachment, you can overcome many common breastfeeding hurdles.
Key Takeaway: Breastfeeding is a partnership. It takes time for you and your baby to learn each other's cues. Be patient with yourself and don't hesitate to ask for help when you need it.

FAQ
How can I tell if my baby is actually swallowing milk?
You can tell by watching the movement of their jaw and listening for a soft "ca" or "glug" sound. A visible swallow often looks like a deep pause in the chin's movement followed by the sound of the gulp. If you only see fast, shallow nibbling without any pauses or sounds, the baby may not be receiving a significant amount of milk.
Is it normal for my nipples to be sore during the first week?
Some "transient" soreness is common as your skin adjusts to the frequent stretching and moisture of breastfeeding. This usually lasts only a few seconds at the start of a feed. However, if the pain is sharp, lasts throughout the whole session, or results in skin damage like cracks or blisters, it is likely a latch issue that needs adjustment.
What should my nipple look like right after the baby unlatches?
A well-latched nipple should look pretty much like it did before the feed, only slightly longer and more stretched out. It should be round and symmetrical. If your nipple comes out looking flattened, wedged (like a new lipstick), or white at the tip, it means the baby was compressing it against their hard palate, indicating a shallow latch.
Does a good latch always mean the baby will get enough milk?
A good latch is the most important factor in milk transfer, but it is not the only one. Even with a perfect latch, things like hormonal imbalances, certain medications, or infrequent feeding can impact supply. Always monitor your baby's weight gain and diaper count (at least 6 wet diapers and 3-4 stools per day by the end of the first week) to ensure they are getting what they need.
