Linguistics

At birth, baby is at the height of their capacities.
A. Tomatis
demonstrated the existence of specific frequencies for each language, which young children can hear and reproduce. When growing up with only one language, a child gradually loses that ability. Their auditory and lingual muscles and organs are not stimulated, and they gradually deteriorate, making it difficult to understand and reproduce certain sounds.
Exposing a child to learning a foreign language from an early age allows them to develop their full physiological potential!
