I have started learning English when I was five. I started learning German when I was ten. I still have trouble when speaking German (I avoid it, actually), but I have no such difficulties when it comes to English. I adore it, I study it, I speak it everyday. This doesn´t change the fact that my native language is Croatian. I speak Croatian perfectly, not because I have studies it in school since I was little, but because it is my mother tongue. I am a native speaker. Nothing can change that. Sometimes it might happen that I can´t remember a certain word or a phrase, but that doesnßt mean that I can´t speak Croatian perfectly.
We had both English and Croatian in primary school since we´d started the first grade when I was six. We managed to study both languages. We didn´t have any problems. And our native language was still the "first", so to say. I believe this is the same with all children: they pick up languages easily. The younger children are, the easier it is for them to learn. The acquisition process happens early on - it´s when children can achieve the almost "native" or "native-like" proficiency. That´s why there are so many bilingual children: they speak BOTH languages. It´s an advantage.
Besides, learning languages helps the brain develop more quickly as the logical connections are being made in between the languages and comparisons... the children who learn languages have fewer problems in school curriculum simply because they think logically. They´re used to it. Same is with playing the piano or something else. It might seem ambitious, but it does help and children don´t have many problems.
I´ve quoted my textbook here, on learning languages and language acquisition
