School tries longer day for kids

In my opinion, having extra hours in kindergardan will not be good for the children, as they are still very young,they might feel too tired after school. If they are forced to do too much learning such as.
mathematics study,they might lose interest about study, as their brains are not developed well to pay attention for such a long time learning also.Then if might affect their life after school because parents will need to spend more time with them. So I do not agree to have extra hours in kindergardan for children.
