How to get my kid ready for primary one?

Have them go through a mock-school day. As primary school is generally longer in duration compared to kindergarten and preschool, have your child go through a whole day of "school" at home. Include the early morning, the various recess breaks and the early sleeping time. You can even get your child to try on his new school uniform and backpack etc. Get him excited for school :)

Can try letting kid to have bridging classes ☺ So they get to expose what primary 1 are going through.

expose kid to different enrichment classes on weekends and full day childcare on weekdays.
