What is Infant Mental Health?
‘Infant mental health describes the social and emotional wellbeing and development of children in the earliest years of life. It reflects whether children have the secure, responsive relationships they need to thrive.’
This encompasses babies’ and young children’s ability to experience, regulate, and express emotions, form secure relationships, and explore their environment.
Why is Infant Mental Health Important?
The emotional well-being of babies and young children lays the foundation for healthy relationships, future mental health, and brain development. Early experiences shape a baby’s brain development and have a lifelong impact on their mental and emotional health. Secure attachments with caregivers help infants develop a ‘blueprint’ for future relationships.
Brain Development in Infancy
The brain develops more rapidly during the first three years of life than at any other time. This period lays the foundations for future development. Babies’ brain development is shaped by their environment, which is hugely dependent on the care they receive from their parents and carers. Positive, nurturing parent-infant relationships are vitally important for healthy emotional, social, and cognitive development.
The Role of Parent-Infant Relationships
Parent-infant relationships start before birth. The foetal brain develops rapidly during pregnancy and is influenced by the physical environment of the mother’s womb and beyond.
Early relational trauma can have a wide-ranging impact on child development and is associated with an extensive range of poor outcomes. Babies and young children’s relationships with their parents / carers influence their social, emotional, language, and cognitive development.
Emotional Regulation and Future Outcomes
Emotional regulation has a significant impact on future relationships and behaviour. Children with better emotional regulation tend to develop better relationships in school with their peers and teachers, which positively affects their education, confidence, and self-esteem.
Young people who can regulate their emotions and behaviours and develop positive relationships are more likely to have good mental health and avoid risky, harmful, or antisocial behaviour.
Supporting Infant Mental Health
Participation
Ensuring that the infant voice is central to service development and delivery is crucial. Involving parents / carers in co-production, development, and delivery of services to meet the mental health needs of babies and young children is essential. Engaging with dads and partners and promoting inclusive and anti-discriminatory practice are also important.
Evidence-Based Practice
Staff development and training around infant mental health are vital for increasing awareness and understanding across the workforce working with children aged 0-5, including during pregnancy. Developing specialist infant mental health roles and supporting services in accessing NHSE funded CYP psychological trainings around infant mental health are also key. Supporting the development of specialised parent-infant relationship teams in all areas is crucial for providing specialist support to babies and their parents/carers and in helping the local workforce to better understand and support parent-infant relationships.
Accessibility
Awareness
Increasing public awareness about the importance of infant mental health and reducing stigma through public health promotions is crucial. Ensuring accessible information around infant mental health is available in different languages on CYP mental health websites, social media and when delivering information during pre-birth appointments with midwives and antenatal classes is necessary.
Accountability
Using appropriate routine outcome measures (ROMs) to demonstrate the effectiveness of interventions and using ROMS in clinical supervision is important. Reviewing outcomes across services on a regular basis to understand trends and identify areas that may need adapting or changing are essential. Eliciting feedback from parents / carers about the service they have received and using ROMs in reports to commissioners can also enhance accountability.
Conclusion
Understanding and supporting infant mental health is crucial for laying the foundation for healthy relationships, future mental health, and brain development. By focusing on participation, evidence-based practice, accessibility, awareness, and accountability, we can ensure that infants and their families receive the support they need for a healthy start in life.
