The idea that bonding happens in a single magical moment at birth is one of the more persistently unhelpful myths in perinatal care. While some mothers do experience immediate and overwhelming attachment, many describe the feeling as gradual, emerging over days, weeks, and even months of caring for their baby. Both experiences are normal.
Healthbooq provides guidance for new mothers navigating the emotional landscape of the postpartum period.
The Biology of Early Bonding
Several biological systems support the development of the mother-infant bond:
Oxytocin. Released during birth, breastfeeding, and skin-to-skin contact, oxytocin promotes maternal behaviours including caregiving responsiveness, gaze towards the infant, and emotional attunement. It also promotes feelings of calm and connection in the mother.
Prolactin. The hormone of milk production also has mood-modulating effects and appears to support maternal behaviour.
Cortisol sensitisation. New mothers show heightened cortisol responses to infant cues — particularly crying — which motivates approach and caregiving. This physiological sensitisation is a normal feature of the postpartum period.
Neurological remodelling. Research by Hoekzema et al. (2017) showed that pregnancy and early motherhood are associated with significant structural changes in the maternal brain, particularly in regions involved in social cognition and theory of mind — changes that persist for at least two years.
What the Newborn Contributes
Bonding is not one-directional. The newborn contributes to the process through:
- Face preference: Newborns show preference for face-like patterns from birth, and within days preferentially attend to the mother's face and voice
- Eye contact: The newborn's visual range is approximately 20–30 cm — the distance to a face during feeding — and sustained eye contact during feeding is a powerful bonding mechanism
- Responsiveness: As the infant's reflexive smiling transitions to social smiling (6–8 weeks), the mother's investment in the relationship is reinforced by clear social feedback
When Bonding Is Slower to Develop
Many factors can slow the development of felt attachment:
- Difficult birth, caesarean section, or complications
- NICU admission and early separation
- Postpartum mood disorders (postpartum depression significantly affects bonding)
- Previous pregnancy loss or trauma
- A baby who is difficult to soothe or who has medical needs
Slower bonding is common and does not predict a worse long-term relationship. What research consistently shows is that bonding is remarkably resilient — it develops as interaction accumulates, regardless of the starting point.
Building the Bond Through Daily Care
Bonding does not require special activities or techniques. It builds through:
- Repeated responsive care (feeding, nappy changes, soothing)
- Sustained eye contact during feeding and quiet alert times
- Skin-to-skin contact, particularly in the early weeks
- Talking, singing, and narrating daily activities
- Responding consistently to crying
Over time, the cumulative experience of being cared for by and caring for this specific person creates an emotionally meaningful, differentiated bond.
Key Takeaways
Bonding between a mother and newborn is a process, not a single event. While some mothers experience an immediate rush of attachment at birth, many do not — and the absence of an immediate emotional response is not evidence of a failure. Bonding develops through repeated interaction, caregiving, and attunement over the first weeks and months. It is robust, and disruptions — including separation at birth, caesarean section, or NICU admission — do not permanently prevent it.
