How to get a good latch

The thing nobody tells you before baby arrives: breastfeeding is a skill. For you and for your baby. You've never done this before and neither have they. A rough start doesn't mean it won't work.

But latch is the part that matters most. A bad latch causes nipple damage, limits milk transfer, and can wreck your supply over time. A good latch fixes most of those problems before they start.

What a good latch actually feels like

There's a lot of generic advice that says breastfeeding "should not hurt." That's mostly true, but it needs a qualifier: the first 10 to 30 seconds of a new latch can be uncomfortable, especially in the early days when your nipples are adjusting. What should not happen is sustained pain throughout the feed.

Signs you have a good latch:

• Baby's mouth is wide open (think yawn-wide, not pacifier-wide).
• You can see more areola above baby's top lip than below the bottom lip (asymmetric latch).
• Baby's lips are flanged out, not tucked in.
• Baby's chin is pressed into your breast and their nose is clear or just barely touching.
• You hear rhythmic swallowing, not clicking or smacking.
• Your nipple comes out round after a feed, not creased, flattened, or lipstick-shaped.
• After the first 30 seconds, there's no sharp pain. Pressure is normal; pain is not.
• Baby stays on without you having to hold them in place the whole time.

Signs of a bad latch

A bad latch often feels obvious. Sometimes it doesn't, especially if you're exhausted and haven't established a baseline for what "okay" feels like yet.

Signs you should break suction and try again:

• Sharp or burning pain that continues past the first 30 seconds.
• Your nipple looks creased, flattened, or shaped like a lipstick tip when baby comes off.
• Baby's lips are tucked under rather than flanged out.
• You hear clicking or smacking sounds during the feed.
• Baby seems to be working hard but not getting much milk (lots of effort, short feeds, still hungry).
• Baby keeps slipping off the breast.
• Nipple cracks, blisters, or bleeding (a sign something has been off for a while).
• Baby only has the nipple in their mouth, not a good portion of areola.

The clicking sound during a feed deserves its own mention. It usually means baby is losing suction and reattaching repeatedly. This limits milk transfer and can cause gas and fussiness. It's also a common sign of tongue tie, which an IBCLC can assess.

How to break suction and re-latch

This is the move most new parents get wrong. Pulling baby straight off the breast without breaking suction first is what causes nipple trauma. The correct way takes two seconds.

1. Insert your finger at the corner of baby's mouth. Slide the tip of your clean pinky finger between baby's gum and your breast, at the corner of their mouth. Angle it slightly toward the roof of their mouth.
2. Wait for the suction to release. Hold your finger still for a moment. You'll feel (sometimes hear) a small release. That's the vacuum breaking. Don't pull baby off before this happens.
3. Remove baby gently. Once suction is gone, your nipple slides out without resistance. Easy.
4. Reposition before trying again. Don't put them back in the same position. Adjust so baby's head is tilted back slightly, chin leading. Their nose should be opposite your nipple (not their mouth) before you bring them on.
5. Lead with baby's chin. Bring baby to breast chin-first. When their chin touches first, they naturally tip their head back, open wide, and take in more tissue. This is the single most reliable fix for a shallow latch.

You might need to do this two or three times on a single feed while you're figuring it out together. That's fine. A slightly longer latch-on is better than a painful one.

Latch positions that help most new parents

Position and latch are not the same thing, but they're connected. A good position makes a good latch much easier to achieve.

Most IBCLCs start new parents with the cross-cradle hold: you hold baby's head in the hand opposite to the breast you're feeding from. It's the most control you'll have over their head position, which matters a lot while you're both learning.

The football hold (baby tucked under your arm, facing up) is worth trying if you had a C-section (no weight on the incision), have larger breasts, or have a baby who arches backward constantly. You also get a clear sightline to the latch, which helps when something feels off and you're trying to figure out why.

Some babies with a weak latch do better in the laid-back position: you recline at about 45 degrees, baby lies tummy-down on your chest. Gravity and the baby's own reflexes do a lot of the work. S.D. Colson's 2008 research in Early Human Development found that this position activates primitive neonatal feeding reflexes that upright holds don't, which can help babies who struggle to stay on.

Side-lying (both of you on your sides, face to face) is useful at night once you've got the hang of it. It's harder to see the latch, so not the best place to troubleshoot. Save it for when things are going well.

Common latch problems and what's causing them

Shallow latch. The most common issue. Baby is only latching onto the nipple, not drawing in enough areola. Usually a positioning problem. Fix: re-latch using the chin-first technique above, and try cross-cradle or football hold so you have more control.

Nipple confusion / flow preference. If baby is also getting bottles and the bottle flow is much faster than the breast, they may latch shallowly or fuss at the breast. Paced bottle feeding can help. It slows bottle feeds down so the difference isn't so jarring. See how paced bottle feeding works if you're combo feeding.

Engorgement. When your milk comes in (usually days 2 to 5), your breasts can become so full that the areola is too firm for baby to latch onto. Hand-express or pump for a minute before latching to soften the areola enough for baby to get a grip. This is temporary. Engorgement typically resolves within a few days as supply regulates.

Flat or inverted nipples. Baby latches onto breast tissue, not just the nipple, so flat nipples don't automatically mean breastfeeding won't work. Nipple shields can help temporarily while baby learns. An IBCLC can assess whether a shield is appropriate and teach you how to use one without affecting supply.

Tongue tie (ankyloglossia). If you're having persistent pain, clicking sounds, poor milk transfer, or a nipple that looks creased after every feed, tongue tie is worth ruling out. It's more common than most people realize. Estimates range from 4% to 11% of newborns according to a 2020 review in Pediatrics. A qualified IBCLC or a lactation-trained pediatrician can assess for it.

When to call an IBCLC

Most latch issues are solvable with positioning adjustments and a few re-latch attempts. But there are situations where you need a professional assessment, not more internet reading.

Call an IBCLC if:

• You have nipple pain beyond the first 30 seconds of every feed, and it hasn't improved by day 4.
• Your nipples are cracked, bleeding, or blistered.
• Baby is back below birth weight at the 2-week check-in, or not gaining weight as expected.
• Baby has fewer wet diapers than expected (fewer than 6 per day after day 5).
• You hear clicking or smacking on every feed despite correct positioning.
• Baby is consistently unsettled after feeds and doesn't seem satisfied.
• Feeds are taking over 45 minutes every time, or baby seems exhausted at the breast before getting a full feed.
• You have signs of mastitis (a hard, red, warm area in the breast with flu-like symptoms).

IBCLCs are different from general lactation counselors or nurses with basic breastfeeding training. The IBCLC credential requires 1,000+ clinical hours and a board exam. The United States Lactation Consultant Association (USLCA) has a directory to find one near you. Many hospitals also have IBCLCs on staff; ask before discharge if you're still in hospital.

Most insurance plans cover lactation consultations under the ACA preventive care mandate. Call your insurer before you pay out of pocket. You may owe nothing.

A note on pain in the early days

Sore nipples in week one are common. Your skin is adjusting to something it has never done before. That's different from the sharp, shooting pain of a bad latch or the burning of thrush (a yeast infection on the nipple, which has its own treatment).

If you're not sure whether what you're experiencing is normal adjustment or a problem, the lipstick test is quick. After baby comes off, look at your nipple. If it's round and symmetrical, the latch was probably fine. If it's creased, pinched, or has a ridge across the middle, it was off and worth correcting.

You do not have to white-knuckle through pain. Getting help early prevents the nipple damage that makes breastfeeding genuinely hard later on.
