Agreed.. take it easy. At the end of the day, this is just kinder...they are not really learning that much, even from so called famous school. His healthy/happy bringing up is more important!
Actually I think Primary school is most important. To get into a good primary school, parent's effort during K1 & K2 is crucial. If parents made a lots of effort, then the kinder doen't really matter so much.
I guess every parent here in HK faces the very similar problems.
In my opinion, schools, teachers and curriculums are the "tools" to equip and to build up our children for a challenging future.
To train their EQ will be as important as to build up their knowledge, please don't stress too much about the choice of school, and don't be too "obsessed" with the "brand name".
As long as your children are happy, healthy and learning, relax and enjoy with them.
