Being bilingual means having total control of two languages. The benefits of bilingualism extend to social, as well as professional life. There are a number of languages spoken throughout the world. Every person knows at least one language which is naturally learnt in childhood. However, children have an inborn talent for new languages. In hundreds of studies, it was proven that the practice of bilingualism is very advantageous in many ways. Bilingualism makes your brain more healthy, complex and actively engaged.
It’s a challenge to keep up with two languages, confusing for children, it might stop you from integrating properly and not developing the language of where you are living.
When you speak in a foreign language, it is natural for others to feel that you are speaking in a language alien to them because you want to bad-mouth them!
We can see the benefits of learning a second language but it must be from early on in a child's life, it can’t be past the age of 7. Children don't only learn a new language but they learn a new culture and expand their minds.
