My office locates in the same building with an English course center so I often see an English teacher around during smoking time. One day I asked him the same questions as you guys did. He truly advised me not to teach or talk to my son in English regardless of how good I'm at English. And I think that's true. We'd better send our kids to good English center providing education services by native speakers.
Totally agree!
Send them to the English native speaker class would be the best option!
Even my son now, sometimes he correct my pronunciation as he claim its wrong! We can talk to them but please do not judge, let the teacher do!
Some have asked about how I teach my son! Actually, he learnt it from his school and friends
The story of my son learning English for somebody might be too aggressive with pain and tear but we had done it well!
In 2008, my son was 2.5 yrs old, I have granted an Australian Award(former Australian Development Scholarship) for Master degree at University of Sydney. At the moment, his Vietnamese was still not so good and no English at all. We had several choices: send him to a Vietnamese based childcare; Uni childcare or Council childcare without Vietnamese staff!
After visiting some childcare, we thought that he might learn English better in an English native environment such as Council childcare. So we had registered him in the council one - closed to our rented house!
The first three months were painful: my son could not communicate with others; he became aggressive and even fight other over toys and tools. My son cried and my wife did too, but the teacher there still believed that they can help him! And after 3 months, he could understand simple context and then he learnt very quickly: after 6 months, he even interpreted the kid conversation to us!
When we came back VN, the first month, he couldn't speak Vietnamese to grandparents but he drop the language also quickly as learning it! Now, we are trying to maintain his English by English only period everyday!
