Lots of good information. Here, in the US, if you don't start speaking any words or sentences by age 2, your kid will be going to speech therapy assigned by the pediatrician. My son didn't really start speaking until 3 years 3 months and I was becoming very worried. As soon as he started preschool, his speaking exponentially increased week after week.
I think it may be a good idea to put him in the K1 class where he can pick up cantonese easily without putting him under duress with the K2 kids.
Now, I understand musical chairs. Thanks for the clarification.
So many things to do especially you mention application for school places usually go 1 year ahead.
Now I need to get all this information sinking in. Thanks!
