Breastfeeding Latch Scoring Guide (Scores A–F) & Top-Up Protocol
A comprehensive assessment framework for evaluating newborn attachment, swallowing rhythm, milk transfer, and supplementary top-up actions.
In the first days of life, weighing or estimating direct breast milk intake can cause unnecessary stress and latch anxiety. The A–F scoring system shifts the focus to observable feeding cues: feeding readiness, attachment firmness, suckling rhythm, swallowing, and breast softening. By scoring these cues at each feed, parents and healthcare providers can objectively determine whether baby received sufficient milk or requires a supplementary top-up feed to safeguard hydration and maternal milk supply.
The Complete Breastfeeding Scoring Matrix (Scores A–F)
Assess your baby at each feeding session and locate the description that best reflects the feed:
| Score | Definition & Observable Cues | Recommended Action & Top-Up Guidance |
|---|---|---|
| Score A Sleepy / No Cues |
Offered the breast, not showing feeding cues, remained sleepy.
Baby does not actively search for the nipple or wake sufficiently to initiate attachment attempts. |
Full top up (while baby is still held at the breast if possible)
Provide expressed breast milk (EBM) or formula as advised by your midwife. Skin-to-skin contact is recommended to encourage awakening. |
| Score B Nuzzling / No Latch |
Interested in feeding, licking, nuzzling however does not latch.
Baby displays feeding cues (rooting, tongue movements, hand-to-mouth) but cannot achieve attachment to the areola. |
Full top up
Calm baby before re-trying attachment. If baby remains unsettled or unable to latch after reasonable attempts, administer full top-up. |
| Score C Brief Latch / Falls Asleep |
Latches onto breast, has a few sucks then releases; might continue on and off like this for several minutes or falls asleep within just a few minutes of latching.
Attachment is fleeting or unstable; no sustained swallowing rhythm is established. |
Full top up
Try breast compressions while baby is latched. If baby quickly slips off or falls into deep sleep without transferring milk, offer full top-up. |
| Score D Pause / Needs Nudging |
Latches and sucks, however sucking is not in a rhythm and baby has long frequent pauses (long enough that mother feels the need to nudge baby to restart sucking): some swallowing observed.
Baby stays attached but requires continuous physical prompting; intermittent milk transfer occurs. |
Half top up
Consider not topping up if mother available for next feed. The baby may wake earlier. |
| Score E Short Feed (5–10m) |
Latches well, long slow rhythmical sucking and swallowing – feed duration between 5 to 10 mins with breasts not softened.
Attachment and suck-swallow coordination are good, but duration is abbreviated and maternal breast remains firm or unchanged. |
Half top up
Consider not topping up if mother available for next feed. However, if baby's demand feeding intervals are regularly longer than 3 hours, offer half top ups. |
| Score F Effective Feed (11–30m) |
Latches well, long slow rhythmical sucking and swallowing – feed duration between 11-30 mins with breasts feeling softened.
Gold standard feed. Sustained deep jaw movement, audible swallowing, infant contentment, and noticeable breast softening. |
No top up
Provided baby displays feeding cues at least 8–10 x per day and is gaining weight. |
Signs of Effective Latch
Check for these observable attachment cues at the breast:
- Rapid attachment: Latches within a few seconds of trying.
- Maternal comfort: No nipple pain after the first 10–30 seconds.
- Close contact: Baby's chin is pressed firmly against the breast.
- Airway clearance: Baby's head is tipped back slightly so the nose is clear of the breast.
- Cheek fullness: Baby has rounded, full cheeks (not sucked in, hollowed, or dimpled).
- Attachment durability: Baby remains attached throughout the feed without repeatedly slipping off.
Signs of Milk Transfer
Verify that baby is effectively drinking and swallowing milk:
- Rhythmic transition: Rapid sucks at first, then slower, deeper sucks with observed & audible swallows.
- Jaw excursion: Whole jaw movements are rhythmic; sucks and swallows with only brief pauses in between.
- Self-detachment: Baby removes himself or herself from the breast when no longer hungry, appearing relaxed and sleepy.
- Maternal sensations: Mother may feel a let-down reflex or a distinct "drawing" sensation in the breast.
- Post-feed satiety: Baby appears contented and satisfied after the feed (not to be confused with lethargy or fatigue).
Understanding Top-Up Feeds: Purpose and Protocol
What exactly is a "top-up feed"?
A top-up is a supplementary feed (offered via bottle, cup, spoon, or supplemental nursing system) given immediately after or alongside breastfeeding. The top-up ensures the infant receives necessary caloric volume and hydration while breastfeeding is still becoming established.
What should be used for a top-up feed?
Feeding guidelines establish the following hierarchy of nutrition for top-ups:
- Expressed Breast Milk (EBM): Freshly expressed colostrum or mature breast milk from the mother is the primary preferred choice.
- Donor Human Milk (DHM): Screened pasteurised donor milk when available in hospital neonatal settings.
- Infant Formula: Commercial infant formula when maternal milk is unavailable or insufficient in volume to meet hydration targets.
Does needing a top-up feed mean breastfeeding has failed?
Not at all. In the early newborn days (especially the first 24 to 72 hours), infant latch mechanics are developing, maternal hormonal signalling is establishing milk volume, and infants may experience birth-related fatigue or jaundice. Providing structured top-ups (Scores A–E) safeguards infant hydration, stabilises blood sugars, and takes the pressure off mother and baby while milk supply matures.
When can top-up feeds be safely tapered or discontinued?
Top-ups are typically reviewed and ceased under the guidance of your child health nurse, midwife, or GP when:
- Baby consistently achieves Score F feeds on demand (at least 8–10 times per 24 hours).
- Baby produces adequate wet and dirty nappies for their day of life (e.g. 6+ heavy pale wet nappies per 24h by Day 5).
- Baby demonstrates consistent weight gain along their WHO percentile curve without requiring supplementary volumes.
This scoring guide is an informational observational tool adapted from healthcare feeding guidelines. It is not a diagnostic device or a substitute for medical evaluation. If your newborn is lethargic, difficult to wake, producing fewer than expected wet nappies, demonstrating jaundice, or experiencing excessive weight loss (>10% of birth weight), seek immediate medical consultation with your paediatrician, GP, or hospital emergency service.
