The way a young child uses language has an impact on their future life. Early language acquisition is a determinant in adult employment, mental health and relationships with others. At the same time there is a broad evidence base that play and learning in the natural environment is beneficial for young children's physical, emotional, social and cognitive development. However, literature about how these two contributions to children's early development intersect and combine, in particular whether and how early language learning in children aged between 3 and 7 years might be enhanced in nature, is harder to find. For this paper, we undertook a systematic literature review to explore and report on research within this important area. Based on an in-depth study of 181 articles, we found that scant literature exists about how children's language is developed within natural environments. Although this appears to be a topic that is discussed in practice-oriented publications, it was found that very few researchers are focusing on and reporting within this area. Twelve papers were thoroughly analysed and three themes identified and discussed; desire to communicate, communication skills and literacy skills. This paper concludes by suggesting areas for future research.
