technically speaking , Sept 1 is the cut-off for most of the schools. also, the kids need to have exactly 3 years old in order to start school. honestly speaking, our bb will most likely to defer one year later.
I don't think it hurts to try those kinders in Kowloon Tong for nursery first and see how it goes. But don't feel too upset if you get rejected becoz after all, our bb is relatively smaller.
same as 小笨豬, I just finished looking kindergarten for big sister. in fact, I was doing that while I was still 坐月. it's not a fun experience.
