I have decided to focus my project on specifically bi/multilingual children’s brain as I have realised, from the sources online, that focusing on the whole concept of bi/multilingual brain is broad and it has many factors which affects it. Given the complexity of the brain, I have understood that being bilingual is an evolving process and the age of acquisition of a language is another factor which affects this process. This, in particular, is the reason why I decided to focus on individuals who learn two or more languages from an early age. I started this project with the intention of focusing on the whole journey of being bi/multilingual and how the brain develops throughout time. However, this is a really long and complex development and also there isn't enough reliable, peer-reviewed researches which track the whole journey. I decided to focus on the sub-topic I am most interested in, the developing brain of a child, and do more in depth research on this. Therefore my question

Children will start to understand simple language and some key sentences as early as six months. At the end of the child's first year, they will have a small vocabulary built up in their brains. All this happens even before they say their first word. Raising trilingual kids. You won't find a better example of how little multilingual children talk. - YouTube In this video there are three children having a conversation with adults, switching between Polish, Italian, English and Spanish throughout the whole video. I tried to find a representative video of how children and in general people tend to communicate when they are able to use different languages in a single conversation. Rather than switching languages between sentences (so one sentence is Polish, for example, and the next sentence in English), the children tend to switch within sentences so a whole sentence in Polish for example, and include within that sentence one or more English words. This shows how the switching pro
