Understanding good attachment
On day 2 after a vaginal birth, the nurse watches how the newborn takes the breast. The question is not about milk volume or maternal pain, but about the mechanics of
latch. In a well-attached baby, the mouth opens wide and the infant grasps a large portion of the breast from below the nipple, not just the nipple tip. This is why
more areola is visible above the upper lip than below the lower lip—the lower jaw is positioned further back on the areola, and the chin rests against the breast .
Key point! The visual asymmetry of areola above versus below the mouth is a direct marker of how deep the breast tissue is drawn into the infant’s mouth. A shallow latch, by contrast, leaves the lips near the nipple base and produces equal or reversed areola visibility.
Why the other options indicate poor attachment
Cheeks drawing inward with each suck means the infant is using negative pressure around the nipple rather than compressing the lactiferous sinuses with the tongue and lower jaw. This hollowing is a classic sign of
nipple-only sucking . Similarly,
lips pushed forward around the nipple base describe pursed or rolled-in lips, not the everted lower lip seen in a deep latch .
Quick, shallow sucks that continue steadily suggest the infant is not getting effective milk transfer; in good attachment, sucking starts rapid to stimulate letdown, then shifts to slower, deeper, rhythmic sucks with audible swallowing .
| Observation | What it indicates | Attachment quality |
|---|
| More areola above mouth than below | Deep grasp of breast from below; lower jaw on areola; chin touches breast | Good |
| Cheeks draw inward | Nipple-only sucking; negative pressure around nipple | Poor |
| Lips pushed forward around nipple base | Pursed lips; lower lip not everted | Poor |
| Quick, shallow sucks throughout feed | No transition to deep rhythmic sucking; ineffective milk transfer | Poor |
Clinical reasoning for the licensure exam
The nurse’s role includes assessing
latch quality as part of breastfeeding support, especially in the first days when nipple trauma and poor milk removal can derail exclusive breastfeeding . Anatomic variations such as a tight upper lip frenulum or ankyloglossia can alter latch mechanics, but the observation described in the correct answer reflects the functional outcome—
the infant’s ability to take breast tissue deeply and asymmetrically—rather than a specific anatomic diagnosis . When the nurse sees more areola above the mouth, the lower lip is typically everted and the mouth is wide open, which supports effective milk extraction and reduces maternal nipple pain .
Watch out! Do not confuse “lips pushed forward” with a normal wide-open mouth. In a correct latch, the lips are flanged outward, especially the lower lip, and the angle of the mouth is wide—not pursed or protruding around the nipple.
