Personally, I think it is quite necessary. 0-3 years old is the golden age of children's development in all aspects. A friend's child goes to an early education class for eight months. In order not to let the baby fall on the starting line, I also signed up for the early education class in the red, yellow and blue parent-child park, which felt quite good. It can not only exercise the baby's physical coordination ability, but also cultivate the child's language communication ability, which is very helpful for the baby's all-round development.
