It’s breast-feeding, not nipple-feeding.

Shallow vs. deep — what changes

A shallow latch traps the nipple between the baby’s gums and the front of the hard palate. Every suckle compresses the nipple. This causes pain immediately and damage within hours: cracking, blistering, bleeding.

A deep latch places the nipple at the back of the baby’s mouth — against the soft palate — with a large mouthful of breast tissue under the lower jaw. The nipple itself is barely compressed. The baby’s tongue and jaw do the work against the areola, not the nipple.

The shorthand: if it feels like the baby is chewing on a straw, the latch is shallow. Break it and try again.

The asymmetrical latch technique

The deep latch is asymmetrical — the baby’s lower jaw is positioned far from the nipple, while the upper lip is close. This gives the lower tongue and jaw maximum room to draw a deep mouthful.

1. Position the baby’s nose at the nipple, not the mouth. Their head should be slightly tipped back so the chin leads.
2. Wait for the wide gape. Touch their lip with the nipple. They’ll open. Don’t latch on a half-open mouth.
3. Hug them in, fast. When the mouth opens wide, bring the baby toward you (not the breast toward them). Their chin and lower lip should land on the areola first.
4. Check the seal. Lips flanged outward like fish lips. Chin pressed into breast. Nose free. A large mouthful, asymmetrical — more areola visible above the upper lip than below.

Breaking a bad latch safely

If the latch is shallow, do not pull the baby off — this will damage the nipple. Use the finger-sweep:

1. Slide a clean pinky finger into the corner of the baby’s mouth.
2. Press gently against their gum to break the suction.
3. Once the seal releases, you’ll feel a small pop. Then ease the nipple out.
4. Reset, wait for the wide gape, and try again.

You may need to break and re-latch 3–5 times in a single feed during the first weeks. That’s normal. Each re-latch is practice for both of you.

When to call a lactation consultant

Don’t wait. The first week is when small problems become large ones. Call an IBCLC (International Board Certified Lactation Consultant) if:

• Pain doesn’t resolve within 3–5 days of birth.
• You see cracked, blistered, or bleeding nipples.
• Your baby is losing more than 7% of birth weight, or not back to birth weight by 2 weeks.
• Feeds consistently take more than 45 minutes or end with the baby still hungry.
• You can’t hear or see swallowing during feeds.

Most hospital systems offer free or low-cost lactation visits in the first weeks. Use them. They’re the experts.

One last thing

Latching is a learned skill for both of you. Most parents are still refining it at 6 weeks. The fact that it took practice doesn’t mean you’re failing — it means you’re doing the thing.
