Benefits of Breast Milk
Time to read: 4 min.
Milk ‘coming in’ normally occurs between 24-72 hours after delivery. It initiates (starts) the increase of larger volumes of milk.
Is defined as little or no maternal perception of breast fullness or leaking at ≥72 hours post-birth.1
Women experiencing delayed secretory activation have 60% higher odds of stopping breastfeeding at 4 weeks.2
There are some conditions or circumstances which put mothers at risk for delayed secretory activation.
These risk factors should be screened for, pre and postnatally as they can negatively impact breastfeeding and overall milk production.
Unplanned/emergency caesarean section10
Stressful or prolonged labour and delivery.11-14
Psychosocial stress / pain1
Postpartum haemorrhage (PPH)1,15
Preterm or late preterm infant1,16
Mother – infant separation17
Delayed first breastfeeding episode18
Formula supplementation within the first 48 hours1,8
Breastfeeding (or pumping) < 8 times in 24 hours1, 18-21
Additional risk factors: infant feeding issues and overuse of pacifiers1, 8

The proper clinical intervention at the right time offers a mother the best chance to achieve her breastfeeding goals.
For some mothers, when at-risk conditions are present, maximising breast stimulation and complete breast emptying through the use of pumping and hand expression in addition to breastfeeding, may be necessary to enable them to achieve adequate breast milk volumes.1
Taking a “wait and see” approach may result in earlier breastfeeding problems.1
Women who experience a delay in the onset of secretory activation may be less able to sustain any and exclusive breastfeeding at four weeks.2
At-risk conditions and delayed secretory activation should be used as a clinical marker to identify women who have a higher chance of breastfeeding difficulties and earlier breastfeeding cessation.2
