The current study brought a bioecological approach to children’s early vocabulary development using data from the Longitudinal Study of Australian Children. Relevant data were available for 2188 children (1119 male) who had a median age of 9 months (M = 9.3 months, SD = 2.1 months) at Wave 1 and a median age of 34 months (M = 34.2 months, SD = 2.5 months) at Wave 2. Results support the developmental importance of joint attention and parent-child book reading as well as the argument that the effects of individual (e.g., parent) and environmental (context) characteristics are primarily indirect, mediated through their impact on proximal processes (Bronfenbrenner, 1995). The evidence indicates that joint attention and parent-child book reading are important facilitators of children’s early vocabulary development.

Vocabulary knowledge is a critical component of school readiness. The current study investigated the extent to which low levels of joint attention in infancy and parent–child book reading across early childhood increase the risk of children having poor vocabulary around the time of school entry. Relevant data from the Longitudinal Study of Australian Children were available for 2369 children (1211 boys) who had a median age of 9 months (M = 9.3 months, SD = 2.1 months) at wave 1 and a median age of 58 months (M = 58.0 months, SD = 2.5 months) at wave 3. As hypothesised, children who had low levels of joint attention at wave 1 were significantly more likely to have poor receptive vocabulary at wave 3. Furthermore, children who had low levels of parent–child book reading across early childhood were two and a half times more likely to have poor vocabulary at wave 3. These results converge with the findings of training studies and underline the importance of educating current and future parents about the pivotal roles of joint attention and parent–child book reading for children’s language development and hence their readiness for school.

A growing body of literature highlights that racial discrimination has negative impacts on child health, although most studies have been limited to an examination of direct forms of racism using cross-sectional data. We aim to provide further insights on the impact of early exposure to racism on child health using longitudinal data among Indigenous children in Australia and multiple indicators of racial discrimination. We used data on 1239 Indigenous children aged 5–10 years from Waves 1–6 (2008–2013) of Footprints in Time, a longitudinal study of Indigenous children across Australia. We examined associations between three dimensions of carer-reported racial discrimination (measuring the direct experiences of children and vicarious exposure by their primary carer and family) and a range of physical and mental health outcomes. Analysis was conducted using multivariate logistic regression within a multilevel framework. Two-fifths (40%) of primary carers, 45% of families and 14% of Indigenous children aged 5–10 years were reported to have experienced racial discrimination at some point in time, with 28–40% of these experiencing it persistently (reported at multiple time points). Primary carer and child experiences of racial discrimination were each associated with poor child mental health status (high risk of clinically significant emotional or behavioural difficulties), sleep difficulties, obesity and asthma, but not with child general health or injury. Children exposed to persistent vicarious racial discrimination were more likely to have sleep difficulties and asthma in multivariate models than those with a time-limited exposure. The findings indicate that direct and persistent vicarious racial discrimination are detrimental to the physical and mental health of Indigenous children in Australia, and suggest that prolonged and more frequent exposure to racial discrimination that starts in the early lifecourse can impact on multiple domains of health in later life. Tackling and reducing racism should be an integral part of policy and intervention aimed at improving the health of Australian Indigenous children and thereby reducing health disparities between Indigenous and non-Indigenous children.

The climate crisis has detrimental impacts on the mental health and wellbeing of children and young people. Psychological effects include feelings of fear, overwhelm, worry, distress, hopelessness and anger; PTSD; depression; anxiety; phobias; panic disorder; sleep disturbances; attachment disorders; learning difficulties; substance abuse; shock and trauma symptoms; adjustment problems; behavioural problems; and, suicidal thinking. First Nations' children and young people are particularly at risk due to loss of place, identity, culture, land and customs informed by kinship relationships with the Earth; while sustainable land use practices and connection to Country and community can enhance climate resilience. In Western Australia (WA), some young people engage in climate activism – including striking from school – to demand government action to address the causes of climate change, including colonisation and capitalism. Climate activism can promote resilience, particularly when children and young people can emotionally engage in the climate crisis; when mental health is systemically supported; when climate communication is transparent and comprehensive; and, when activism is informed by the knowledges and wisdoms of First Nations peoples and grounded on Country. This article is co‐authored by WA young people, Aboriginal and non‐Aboriginal academics, activists and practitioners engaged in youth, mental health and climate justice spaces. We argue for structural change to address the causes of the climate crisis, alongside enhanced evidence and approaches to appropriately support the mental health of children and young people. Furthermore, we support the call of Aboriginal peoples to ensure culturally appropriate, place‐based responses based in caring for Country.
