Introduction to Infant and Toddler Mental Health

Across the world, 10% to 20% of children and adolescents suffer from mental health disorders (Bethell et al., 2022; Kessler et al., 2007) that can have a severe, negative impact on children’s development and their long-term capacity to live healthy, productive and fulfilling lives (Lyons-Ruth et al., 2017). Mental health disorders have a profound impact on all aspects of health, happiness and productivity. As mental health difficulties early in life have a significant impact on the future health trajectory of an individual, it is essential to build the foundations of good mental health during the critical period of infancy and toddlerhood (Lewis et al., 2014; Moore et al., 2017). This section will discuss mental health and adverse childhood experiences during infancy and toddlerhood and the role of caregivers in supporting the development of optimal mental health.^{^[1]}
