Although starting to learn a foreign language at a young age is advantageous, learning a foreign language can take place at any age. Young children have flexible auditory processing mechanisms that are able to assimilate any sound system, be that of the mother tongue or of a foreign language. If the rules of linguistic integration are applied in the family and social environment, there is no reason for young children not to become multilingual, or at least bilingual, in a short period of time.

When parents have different mother tongues, each one must address the children in his or her native language. A baby knows very well how to capture the essential sound variations of each language and does not get confused with the different phonological systems, either at the level of listening, or at the level of the reproduction of sounds. He tunes his ear to the particular sound system of the language he hears spoken by a parent at a particular moment and constantly repeats sounds and phonemes in order to gradually create the phrases that will allow him to express himself correctly in his social environment.

The foreign language preparation program consists of two cycles, a cycle of 15 two-hour sessions (at least 3 times a week), which lasts 5 weeks, and a second cycle of 8 two-hour sessions (also 3 times a week), which lasts 2 ½ weeks. The aim of the foreign language preparation program is to prepare the ear to integrate the sounds of that language the person wishes to learn.
