Hi again, Suki.
I was hoping to receive some additional information from you, but I will answer your question now, and if you have any additional questions, simply 'Reply.'
If you would like your son to attend nursery school when he is 2 or 3 years old, it would be best to put him on a list for the particular schools your are interested in, as soon as possible, and make sure to indicate the age and year, for which you are requesting admission.
For Primary School, which admits children at 4 or 5 years old, you can do the same thing: put him on the list of the schools of your choice as soon as possible, to increase your chances of getting into your desired school. Here is much more detailed information and click on all the links that pertain to your situation:
