Considering by region, if the educational resources in your region are insufficient, you have schools with good economic conditions, and your region has higher educational plans (such as going abroad) after economic and cultural development, you think it is necessary to attend early education classes to strengthen children's competitiveness. There are many shortcomings, but in a word, you don't want your children to be left at the starting line when all the children around you are on the bus;
If the competition in your area is not fierce, your children are well developed, you have no resistance to going to school and are satisfied with your children's future planning, then early education classes are unnecessary. You can sign up for a short class and let the children taste the atmosphere of school, which is almost the same. After all, early education classes are still a kind of pressure on children, and it is not without negative effects on going to school in the future. You can think about it more.
For example, in the primary school near me, children who can sing English songs in grade one run around. At this time, I feel that children must go to early childhood classes in the future, otherwise they will not be able to keep up with children of the same age.
