Getting your baby to open wide before latching comes down to triggering their natural reflexes at the right moment and bringing them to the breast with the right angle. A shallow latch, where the baby clamps down mostly on the nipple, is the leading cause of breastfeeding pain. About 76% of breastfeeding women experience latch-related nipple pain, and roughly 30% stop breastfeeding within 12 weeks because of sore, cracked, or bleeding nipples. The good news: a few specific techniques can help your baby take a much bigger mouthful of breast.
Why a Wide Gape Matters
When a baby latches shallowly, their tongue sits too far forward in the mouth. The nipple tip rubs against the hard palate with every suck, creating friction that leads to soreness, cracking, blistering, and blanching. If your nipple comes out of your baby’s mouth looking flattened or wedge-shaped (sometimes called a “lipstick” shape), that’s a reliable sign the latch was too shallow.
A deep latch looks and feels different. The baby’s jaws close on the areola rather than the nipple itself, and the nipple points toward the roof of the mouth where the palate is soft. Their tongue extends over the lower gum and partially wraps around the breast, creating a cushion that protects the nipple and draws milk efficiently. You’ll see their lips flanged outward like a fish, their chin pressing firmly into the breast, and their nose just barely touching or hovering close to the skin. Swallowing sounds replace the clicking or smacking that often signals a shallow latch.
How to Trigger the Widest Mouth Opening
Babies are born with a rooting reflex: stroke their cheek or brush your nipple across their upper lip, and they’ll turn toward the stimulus and open their mouth. But a small, tentative opening isn’t enough. You want the full gape, the kind where their mouth drops wide like a yawn. To get it, lightly brush or tickle your nipple from the baby’s nose down to their upper lip, then wait. Don’t rush. Many parents latch at the first sign of an open mouth, but holding off another half-second for the mouth to open at its widest makes a dramatic difference in how much breast tissue the baby takes in.
Timing is everything. Aim your nipple just above the baby’s top lip so they have to reach up slightly. Their head should be tilted back a little, with chin leading and nose free. The moment you see that wide gape, bring the baby swiftly to the breast (not the breast to the baby). A quick, confident movement in that split-second window is what separates a shallow latch from a deep one.
The Asymmetric Latch Technique
A good latch isn’t centered. You want more of the areola in the baby’s mouth on the lower lip side and a bit less on the upper lip side. This asymmetry positions the nipple so it points toward the soft palate and keeps the baby’s tongue where it needs to be, underneath the breast, doing the work of drawing out milk.
Think about how you’d bite into an overstuffed sandwich. You wouldn’t center it in your mouth. You’d place your lower jaw first, then open wide to get the top in. Your baby’s latch works the same way. Their lower jaw should land on the breast well away from the nipple, anchoring deep into the areola. Then the upper lip follows, and the nipple rolls in last. Position the baby so their nose and eyes are roughly opposite the nipple before latching. This gives them room to tilt back, reach forward, and anchor chin-first.
The Flipple and Breast Shaping
If your baby keeps getting a shallow latch despite good timing, two hands-on techniques can help. The first is breast shaping, sometimes called a “sandwich.” With your free hand, compress the breast between your thumb and fingers so it matches the shape of the baby’s mouth, like flattening a sandwich to fit. Hold the compression parallel to the baby’s lips (thumb on top, fingers below, or the reverse depending on your position). This gives the baby less tissue to manage and makes it easier to get a deep mouthful.
The second technique is sometimes called the “flipple.” As your baby opens wide, use your thumb to press the nipple upward and tuck the lower part of the areola into the baby’s mouth first. The nipple goes in last and unrolls against the palate. You can then slip your finger out. This method is especially helpful for larger breasts or flat nipples, where the baby has a harder time drawing enough tissue in on their own. Keep your fingers well away from the spot where the baby’s chin and lower jaw need to rest so nothing blocks them from sinking deeply into the breast.
Try Laid-Back Breastfeeding
Sometimes the best thing you can do is lean back and let your baby’s reflexes take over. Laid-back breastfeeding (also called biological nurturing) means reclining at a comfortable angle, placing your baby tummy-down on your chest, and letting them find and latch onto the breast with minimal guidance. In this position, gravity keeps the baby’s body pressed against yours, and the skin-to-skin contact activates a whole set of primitive reflexes, including bobbing, rooting, and self-attachment, that babies are born knowing how to do.
Research shows that the laid-back position leads to a higher proportion of successful latching and self-attachment compared to more upright positions. It also reduces nipple problems. This approach works from the day of birth all the way through weaning, and it can be especially useful when other positions aren’t clicking. If you’ve been sitting bolt upright and wrestling your baby into position, try reclining to about 45 degrees. You may find your baby latches more deeply with less effort from both of you.
What to Do When Engorgement Gets in the Way
Even a baby with great technique will struggle to latch onto a breast that’s swollen and firm. Engorgement makes the areola taut, and the baby’s mouth simply slides off or clamps down on just the nipple. A technique called Reverse Pressure Softening can solve this quickly.
Lie down or lean back so your breasts rest flat against your chest. Place your fingertips around the base of the nipple and press gently but firmly inward for 30 to 50 seconds. Then drag your fingers outward while still pressing. Rotate your finger positions around the nipple and repeat until the areola feels noticeably softer. The softening only lasts about 5 to 10 minutes before fluid returns, so latch the baby on right away. If your breasts are very swollen, the one-handed version works well: curve all your fingertips around the nipple base (keep nails short) and press steadily for 50 seconds or longer. Do this before every feeding until latching becomes consistently easy.
When the Latch Still Isn’t Working
If you’ve tried these techniques patiently and your baby still can’t open wide enough or maintain a deep latch, tongue-tie is worth considering. Tongue-tie (a tight or short band of tissue under the tongue) is the most commonly identified physical cause of poor latch. It restricts the tongue’s ability to extend over the lower gum and cup the breast, which limits how deeply the baby can latch and how efficiently they transfer milk. Signs include a clicking sound during feeding, the baby slipping off the breast repeatedly, poor weight gain, and persistent nipple pain despite good positioning.
Not every tongue-tie causes feeding problems, and not every latch issue is caused by tongue-tie. But if you’ve worked through positioning and technique with no improvement, an evaluation by a lactation consultant or pediatrician experienced with oral ties can identify whether this is the barrier. When tongue-tie is genuinely interfering, a simple release procedure often produces an immediate improvement in latch depth.
Signs You’ve Got It Right
- Lips flanged outward like a fish on both the top and bottom.
- Chin pressed into the breast with the nose lightly touching or just above the skin.
- More areola visible above the upper lip than below the lower lip.
- No pain after the first few seconds. A brief tugging sensation at latch is normal in the early days, but ongoing pinching, burning, or sharp pain signals the latch needs adjusting.
- Audible swallowing rather than clicking, smacking, or a lot of visible jaw movement without swallows.
- Your nipple comes out round, not creased, flattened, or wedge-shaped.
If the latch feels wrong, break the seal by sliding a clean finger into the corner of the baby’s mouth, gently pull them off, and try again. Relatching as many times as needed is always better than pushing through a painful, shallow latch. Most babies get faster at opening wide and latching deeply as the weeks go on, especially when they learn that a deep latch means easier, more satisfying feeding.
