my girl (0408) was admitted in KL am class. i only speak Cantonese with my girl. My girl didn't complete all the tasks. For example, she didn;t know how to play the puzzle, but I told the teacher that she never played this before, and she said it's understandable and ok. Not sure but perhaps it would be helpful if you explain to the teacher for the comimg interviews that your baby for the time being could only understand english (teach him cantonese later) and if they don;t mind, you would do the transaltion? After all, they are still babies, teachers should understand that.
