Caesarean section (CS) is the most frequently performed obstetric surgery. In recent years, the rate of CS has been increasing (Antoine & Young, 2020). Compared with vaginal delivery, CS is associated with a stronger stress response in pregnant women, which can not only increase the operation risk, but also affect the postpartum recovery (Madsen et al., 2013;Molgora et al., 2020). Studies have suggested that the adverse psychological and emotional state of mothers during pregnancy and childbirth can affect the neurobiology and behaviour of the offspring, and this effect may continue until adulthood (Sandall et al., 2018).
