Drawing upon the latest research around childbirth experiences and baby behaviour and development, this final chapter draws conclusions from three original research studies that investigated the links between mothers’ perceptions of childbirth and their babies’ behaviour. Findings from a survey of a thousand mothers highlighted connections between physical and psychological elements of childbirth, maternal confidence, perinatal mental health and early infant temperament. Interfering with the mother and baby’s interwoven physiology through stress-inducing medical interventions such as assisted birth or emergency caesarean section can save lives. However, these interventions predicted poorer postnatal mental health, lower maternal confidence and more unsettled newborn baby behaviours; therefore, they should only be used when required rather than as standard practice (WHO, World Health Organization recommendations: intrapartum care for a positive childbirth experience, 2018). Predominantly, it was the mother’s negative birth experience (anxious and afraid birth emotions) together with postnatal distress and depression that predicted ongoing unsettled, irritable and irregular baby behaviour. Conversely, a positive, well-supported birth experience predicted overall calm, easy, alert and responsive behavioural style in the 0–6-month-old infant. Considering the findings from in-depth interviews with 40 mothers, midwives, doulas and health visitors, this link between the mother’s subjective birth experience and early infant behaviour seems to be mediated by emotional support during childbirth, parents’ postnatal mental health, and the impact of these factors on parent-infant bonding. To achieve the best long-term physical and psychological outcomes for mother and baby, we need to protect their interwoven physiology during childbirth and postnatally as much as possible given the circumstances of the birth. Midwives are in an ideal position to provide the physically, psychologically, socially and culturally safe, respectful, kind, compassionate and personalised care that women want and need to avoid trauma and have a positive birth experience, regardless of birth mode. This type of maternity care is particularly important in the event of any complications arising, and essential for more vulnerable parents, including younger parents, those from poorer backgrounds or ethnic minorities, and parents with a disorder or disability.
