How to Tell If Your Baby Is Latching Well
One of the most common concerns new mothers share with me in consultations is: "Is my baby actually latching properly?" It's a fair worry — a poor latch is the single biggest cause of sore nipples, low milk transfer, and leads to low milk supply eventually. The good news: latch quality is something you can assess, correct, and improve, usually within the first few days.
Signs of a Good Latch
When your baby is latching well, you'll notice most or all of the following:
- Wide-open mouth — Baby's mouth should be open as wide as a yawn before latching, not pursed like a kiss.
- Asymmetric latch — More areola visible above the nipple than below. Baby's chin should press into the breast, not the nose.
- Lips flanged outward — Both lips, especially the lower lip, should be rolled out (flanged), not tucked in. Upper lip can be neutral also.
- Rounded cheeks — Hollow, sucked-in cheeks are a red flag. Full, rounded cheeks mean baby is drawing milk effectively.
- Audible swallowing — After the initial rapid suck-suck-suck, you should hear rhythmic swallowing — a soft "kuh" sound.
- Comfortable for you — You may feel a strong tugging sensation, but latch should not be painful. Pinching, burning, or sharp nipple pain at any point is a signal to unlatch and try again.
Signs the Latch Needs Adjustment
- Nipple appears creased, flattened, or lipstick-shaped after feeding
- Clicking or smacking sounds during nursing
- Baby frequently falls off the breast or seems frustrated
- Feeds feel endless with no obvious swallowing
- Your nipples are cracked, blistered, or bleeding
- Baby is not gaining weight as expected
How to Break and Redo a Latch
If the latch doesn't feel right, break it first — never pull baby off the breast. Slip a clean pinky finger into the corner of baby's mouth to release the seal, then try again. Position baby so their nose is level with your nipple before latching so that chin is pressing against your areola; this encourages them to tilt their head back and open wide.
Positioning Matters as Much as Latch
Latch and positioning are inseparable. Whether you use the cradle hold, football hold, or laid-back nursing, the principle is the same: baby's whole body should be turned toward you (tummy-to-tummy), well-supported, and not rotated or straining at the neck. A baby who has to turn their head to reach the breast will struggle to latch deeply.
When to Get Support
If you're experiencing persistent nipple pain, your baby is losing weight after day 4–5, or feeds feel chaotic and unsettled, please don't wait. Latch issues are almost always correctable — but they're much easier to address in the early days than after weeks of compensating.
A one-to-one consultation gives us time to observe a full feed, identify exactly what's happening, and walk you through corrections in real time. Book a Postnatal Latch & Feeding Consult and let's get feeding on track together.
