Different parents may have different views on this issue. Some possible pros and cons are as follows:

The advantage of attending a foreign teacher class is that it can expose children to pure English pronunciation and language environment, cultivate children's interest and confidence in English, and lay a good foundation for future English learning.

The disadvantage of foreign teaching is that it may increase the financial burden of children and parents, and the quality of foreign teaching may not be guaranteed. Some foreign teachers may not have a high level of English, or they may not take care of their children's emotions and safety.

You can comprehensively consider whether it is necessary to teach foreign classes according to your own and your child's actual situation. You can also ask your child his own opinion to see if he likes to communicate with foreign teachers.

However, I have always felt that children are so young, and most of them grew up in the environment of China. Foreign teachers' classes in kindergartens are really a drop in the bucket and unnecessary.
