I believe that children learn fastest and easiest in the first 3 years, so we started attending Shichida (in KL, same system as S'pore) when son was 14 months old. We wanted to start at 10 months old but timing could not fit in. After 2 terms, I am very pleased with the methodology, my boy enjoys every class and has learnt a lot. We do home practice every day, which is recommended by the method.
Shichida Method is more than academics, it teaches parents how to show love to the child so that he can absorb input and be a well-behaved child. It also teaches us that a child should aim for success so that he can contribute to the society. I certainly recommend the method.
