The Latch: Everything You Need to Know

What a good latch looks and feels like, how to get one, and what to do when it’s not working.

If breastfeeding is a skill – and it is – then the latch is the foundation. Get this one thing right, and most of the other common breastfeeding difficulties either don’t appear or are much easier to solve. Get it wrong, and pain, poor milk transfer, and supply problems can follow quickly.

The good news: latch is learnable. Your baby was born with the instincts for it. You were built for it. It sometimes takes a few days of practice – and occasionally a little outside help – but a good latch is almost always achievable.

This article will walk you through exactly what a good latch looks and feels like, how to get one step by step, and what might be going wrong if it’s not working.

Why Latch Is Everything

When your baby latches shallowly – meaning they have only the nipple in their mouth rather than the nipple and a large portion of the areola – two things happen simultaneously and neither is good.

First, it hurts. The nipple gets compressed against the hard palate, which is exactly as uncomfortable as it sounds. This is the source of a huge proportion of breastfeeding pain.

Second, milk transfer suffers. A deep latch allows your baby’s tongue to compress the milk ducts behind the areola, drawing milk out efficiently. A shallow latch means your baby is essentially sucking on the tip of the nipple – working hard for very little milk. This leads to a frustrated baby and, over time, a body that receives less demand and produces less supply.

The Risk of a Poor Latch

One that goes uncorrected is one of the most common – and most overlooked – contributors to genuine low supply. If you have been worried about your supply and latch has been a struggle, it is worth addressing the latch first before assuming supply is the underlying problem.

It is also one of the most common pathways to early breastfeeding cessation. Not because breastfeeding failed – but because no one caught and fixed a correctable problem.

What a Good Latch Looks and Feels Like

The most important thing to understand:

how a latch feels is more important than how it looks. You can have a latch that technically checks visual boxes but is still causing pain – and pain means something needs adjusting. Trust your body.

Signs of a Good Latch – What You Want to See and Feel

• No lasting pain. You may feel a brief, sharp sensation in the first few seconds as the breast tissue is drawn in. This is normal and should fade within about 30 seconds. If pain continues throughout the entire feeding, the latch needs attention.
• Wide open mouth. Your baby’s mouth should be open as wide as a yawn – not just slightly open. A wide gape is what allows them to take in enough breast tissue for a deep latch.
• Lips flanged outward. Both lips – especially the bottom lip – should be turned out like a fish, not tucked in. Tucked lips break the seal and cause friction.
• More areola visible above the top lip than below. Your baby’s mouth should be asymmetrically placed – more of the areola should show above the lip than below. The chin should be pressed into the breast, with the nose free.
• Chin pressing into the breast. When the chin makes firm contact with the breast, it naturally triggers a wider gape. This is the key reflex that creates a deep latch.
• Audible swallowing. You should hear rhythmic swallowing – a soft gulp or k-ah sound – especially after the milk lets down. This is your confirmation that milk is being transferred.
• Round nipple shape after feeding. After your baby releases the breast, your nipple should look elongated but essentially round. If it looks flattened, creased, wedge-shaped, or like the tip of a new lipstick, the latch was too shallow and the nipple was being compressed.
• Baby’s jaw moving rhythmically. You should be able to see the jaw working – a deep, slow, rhythmic movement. Quick, shallow, fluttery sucking without jaw engagement suggests the latch isn’t deep enough.

Signs of a Poor Latch – What to Watch For

• Pain that persists past the first 30 seconds and continues throughout the feeding
• Nipple looks compressed, wedge-shaped, or blanched after feeding
• Clicking or smacking sounds during feeding – this means suction is being broken and re-established repeatedly
• Tucked or rolled-in lips rather than flanged outward
• Baby’s cheeks sucking inward rather than staying full and rounded
• Baby slipping off the breast repeatedly during a feeding
• Cracked, blistered, or bleeding nipples after the first few days
• Baby consistently unsatisfied after long feeding sessions despite adequate positioning

How to Get a Good Latch: Step by Step

There is no single “correct” position. What matters is that your baby’s body is aligned, they can open wide, and their chin makes contact with your breast first. Here is a straightforward approach that works for most mother-baby pairs.

1. Start calm

A hungry but not frantic baby latches better. Watch for early hunger cues – rooting, hand-to-mouth, stirring – and offer the breast before crying starts. A crying baby is a tense baby, and tension makes latching harder for both of you. If your baby is already upset, take a moment to calm them first: skin-to-skin contact, gentle rocking, a finger to suck on briefly.

2. Get comfortable and sit up straight

Slouching or hunching over your baby makes latching harder. Sit up, support your back, and bring your baby to your breast – not your breast to your baby. A nursing pillow can help bring your baby to the right height without you having to lean.

3. Align ear, shoulder, and hip

Your baby’s head, shoulder, and hip should be in a straight line, facing your body. Their head should not be turned to the side. Their whole body should be facing yours – tummy to tummy.

4. Support your breast

Hold your breast in a C-shape (thumb on top, fingers underneath) or U-shape (fingers on either side), keeping your fingers well back from the areola. This supports the breast and makes it easier for your baby to latch deeply.

5. Aim nipple toward the nose, not the mouth

Position your nipple pointing slightly upward, toward your baby’s nose rather than straight at their mouth. This encourages them to tilt their head back and approach chin-first, which is exactly what you want.

6. Wait for the wide gape

Tickle your baby’s lips with your nipple to encourage them to open wide. Wait for a big, yawn-like opening. Do not latch onto a partially open mouth – this is where shallow latches begin. Patience here pays off significantly.

7. Bring baby onto breast chin first

Once the mouth is wide open, quickly bring your baby onto the breast – chin first, lower jaw first. The chin should make contact before the upper lip. This is what triggers the deep latch reflex. You are bringing baby to breast, not pushing breast into baby.

8. Check and adjust

Once latched, check that lips are flanged, chin is pressed into the breast, and that feeding feels like pulling or tugging rather than pinching or pain. If anything is off, break the suction gently by inserting a clean finger into the corner of your baby’s mouth and try again. Never pull the baby off without breaking suction first.

Breaking the Latch Safely

To break the latch, slide a clean finger into the corner of your baby’s mouth, between the gums, and gently turn it a quarter turn to release the suction. Never pull your baby off the breast without breaking suction first – this is how nipple damage happens.

When the Latch Isn’t Working

Sometimes positioning adjustments alone aren’t enough. Here are the most common reasons latch problems persist, and what to do about them.

Engorgement

When breasts are very full and firm, the nipple and areola can flatten, making it hard for your baby to get a deep latch. Before feeding, try hand expressing or pumping for a minute or two to soften the breast enough for your baby to latch. Warm compresses beforehand can also help.

Flat or Inverted Nipples

Flat or inverted nipples can make latching more challenging, but many mothers with flat or inverted nipples breastfeed successfully. Techniques like breast shaping, nipple stimulation before feeding, or a breast pump used briefly to draw the nipple out can help. A nipple shield – used under the guidance of a lactation consultant – can also be a helpful bridge while latch improves. Note that nipple shields can reduce transfer if not monitored.

A Sleepy Baby

Newborns are notoriously sleepy, especially in the first two weeks. A baby who falls asleep within minutes of latching may not be transferring enough milk. Techniques to keep a sleepy baby feeding include undressing them down to a diaper for skin-to-skin stimulation, tickling the feet or under the chin, switching sides when sucking slows, and breast compression to keep milk flowing and baby engaged.

Tongue Tie or Lip Tie

If you have tried every positioning technique and pain or poor milk transfer persists, tongue tie or lip tie may be worth investigating. A tongue tie (ankyloglossia) restricts the tongue’s range of motion, preventing the baby from cupping the breast properly. A lip tie restricts the upper lip’s ability to flange outward. Both can cause clicking sounds, poor milk transfer, slow weight gain, and significant nipple pain.

Not every suspected tongue tie requires treatment – evaluation by a qualified provider who understands the full picture of breastfeeding function is important before any intervention.

Latch Pain After the First Two Weeks

Some nipple tenderness in the first one to two weeks is normal and expected – your body is adjusting to a new demand. Keeping nipples moisturized with a lanolin-based nipple cream or a medical-grade balm after feedings can help manage light soreness and prevent cracking. There is no need to wipe it off before feeding – products designed for nursing are safe for baby.

But pain that persists beyond two weeks, worsens, or begins after a period of comfortable feeding is a different conversation entirely and should not be dismissed. Beyond latch issues, persistent pain can indicate thrush (a yeast infection), bacterial infection, or Raynaud’s phenomenon affecting the nipple. These are all treatable – but they require identification first.

A comfortable latch matters, but milk transfer matters too. If you are unsure whether baby is getting enough at the breast, read how to tell if your baby is getting enough milk.

Breastfeeding Positions That Support a Good Latch

No position is universally best. The right position is the one where your baby can open wide, approach chin-first, and you are both comfortable. Here are the most commonly used:

Cradle hold: Baby lies across your body, tummy to tummy, supported by the arm on the same side as the breast you’re nursing from. Classic and intuitive, but can make positioning control trickier for newborns.

Cross-cradle hold: Baby lies across your body but is supported by the opposite arm, giving you more control of the head for guiding the latch. Often recommended for newborns and early latch learning.

Football hold: Baby is tucked under your arm like a football, facing up, with their legs behind you. Excellent for mothers who had a cesarean, have larger breasts, or are feeding twins. Gives good visibility and head control.

Laid-back / biological nurturing: You recline at roughly a 45-degree angle, baby lies tummy-down on your chest. Gravity helps hold the baby in position and activates their rooting reflexes. Particularly useful when other positions are causing pain or when latch is difficult.

Side-lying: Both mother and baby lie on their sides, facing each other. Useful for nighttime feeds or after cesarean. Requires good positioning to ensure a deep latch.

The Bottom Line

Latch problems are one of the most common correctable causes of breastfeeding difficulties. Pain, poor weight gain, supply concerns, and early weaning are all frequently downstream of a latch that was never quite right – and never got the attention it needed.

The latch can almost always be improved. Sometimes it just takes a small adjustment. Sometimes it takes a few days of practice. Occasionally it takes a professional set of eyes.

If you are in pain, please do not white-knuckle through it. Persistent pain is information. It is your body telling you something needs to change – and change is possible.
