The time for a baby to attend an early education class varies from person to person, but it is usually recommended to start in the sixth month after the baby is born. This is because during this period, the baby's sensory and cognitive abilities begin to develop, and they need more stimulation to promote brain development.

However, this does not mean that all babies need to attend early education classes. Parents can decide whether to let their baby attend early education classes according to their own and their baby's specific situation. For example, if the baby has enough opportunities for stimulation and interaction at home, or the family's economic conditions are limited, then you can consider postponing the time of attending the early education class.

In short, parents should decide when to go to kindergarten according to their baby's needs and family situation, instead of blindly following the expectations of others or society.
