Early language acquisition has an impact on each aspect of young children’s non-physical development. It contributes to their ability to manage emotions and communicate feelings, to establish and maintain relationships, to think symbolically, and to learn to read and write.The UK prevalence rate for early language difficulties is between 5% and 8% of all children, and over 20% for those growing up in low-income households. The high prevalence among disadvantaged children is thought to contribute to the achievement gap that exists by the time children enter school and continues until they leave.
