B's language development

How do you say "Banana"?

Somehow he can't say "banana" but he says "bantanana".

Before B went to school, the only Mandarin he knew was his name. And that was after drilling him so that he would know when his teacher was calling him. He was learnt two new phrases.

加油! 加油!

This is what his classmates would say during outdoors to encourage his friends to run.

不要

His favorite phrase these days when he doesn't want to do something.
