when will you start sending your child for classess ? do you think they learn much when they are so young? Will it cause stress to them as some of my friend send child to classess as young as 6-8months

It really depends up to individual. Some people feel that the kids should be playing at these age while some feel that these is the prime age for them to learn some good knowledge. From my point of view, classes are okay. My boy enjoys his classes and we do not force him. We often check with him whether is the class fun, is it something he likes? Does he still wants to go to the classes? Of course as parents we need to be open minded and positive about it.
