Northern Ireland's Public Health Agency launched an updated Infant Mental Health Framework and Action Plan on 5 March. Health Minister Mike Nesbitt announced the plan at a conference in Belfast. The framework covers interventions from the antenatal period to babies aged three years.

Senior representatives from health, education, early years, government and community organisations attended the conference. The plan aims for coordinated services across health, education and community sectors.

Emily Roberts, Interim Director of Nursing at the Public Health Agency, stated that infant mental health covers social and emotional development from pregnancy to age three. She said research shows early attachment and caregiving affect future mental health, physical health, education and social outcomes. Roberts noted early intervention cuts risks from stress and adversity in pregnancy and early childhood.

Health Minister Mike Nesbitt said experiences in a baby's first 1,000 days shape later outcomes due to rapid brain development. He called for work across departments, sectors, agencies and disciplines to aid infant attachments and relationships.

Frances Lyons, Head of Research and Evidence and Director in Northern Ireland at the National Children's Bureau, said the framework needs targeted support for families facing poverty, poor mental health or trauma. She stated aid from pre-birth to age three aids infant wellbeing.

In 2024, 19,416 babies were born in Northern Ireland. Around 23% of children live in relative poverty and 20% in absolute poverty before housing costs.
