Maternal mental health in the postpartum period is a major public health issue in France. The 2021 National Perinatal Survey highlights high prevalence rates of mental health disorders among mothers, with 27.6% experiencing anxiety disorders, 16.7% experiencing depressive disorders and 5.4% having suicidal thoughts. Between 2016 and 2018, suicide was also the leading cause of maternal mortality in the year following childbirth, underscoring the severity and frequency of these disorders. In response, international guidelines, notably those of the World health Organisation (WHO), as well as national policies such as the 'First 1,000 Days' strategy, emphasise the importance of early, enhanced and individualised postnatal support. In France, this postpartum care tends to be structured around the Early Postnatal Interview and the recommended use of validated screening tools such as the Edinburgh Postnatal Depression Scale (EPDS).

However, the quality of postpartum care depends not only on screening and clinical follow-up, but also on organisational and environmental factors. Among these, the arrangements for maternity ward visits constitute a potential determinant of patients' experiences, likely to influence both their mental state, their rest, the establishment of breastfeeding and, indirectly, the health of the newborn. The exceptional measures implemented during the Covid-19 pandemic, notably the restriction of visits, have shown generally favourable effects, with improved satisfaction among patients and healthcare staff, better conditions for rest, facilitation of breastfeeding and a perceived improvement in working conditions.

However, these data were collected in an exceptional health context, which may introduce biases linked to the social, emotional and organisational constraints specific to this period. Their extrapolation to routine practice therefore remains uncertain. Furthermore, in the absence of specific national guidelines governing maternity ward visits, the current regulatory framework remains unclear and practices vary between institutions, often relying on local decisions that have not been scientifically evaluated.

Against this backdrop, the VISIMAT study aims to characterise maternity ward visiting arrangements outside of any exceptional circumstances and to assess their impact on the health of mothers and newborns, as well as on healthcare workers' working conditions. Its aim is to provide a scientific basis to inform the development of standardised recommendations and prevention messages.

Inclusion Criteria:

• Adult female patient (aged 18 or over),
• Female patient admitted to the maternity ward with her newborn baby or babies,
• Length of stay in the maternity ward of 48 hours or more,
• Female patient who has been informed about the study and has given her free, informed verbal consent to participate in the study.

Exclusion Criteria:

• Patients who have already participated in this study,
• Patients whose newborn(s) are hospitalised in neonatal units, neonatal intensive care units or neonatal resuscitation units,
• Patients who have given birth to three or more newborns (triplets or more),
• Patient whose newborn(s) has/have died,
• Patient unable to understand spoken or written French, making self-assessment impossible,
• Patient under guardianship, curatorship or placed under judicial protection,
• Patient not covered by the French social security system.

All patients admitted to the maternity ward with their newborn baby or babies will be invited to take part in the study
