My family is using this app, but I think it can be bought according to the baby's characteristics, because there are free early childhood education courses at home, you can also try the courses you need to buy. If you see the right one, you can buy it. The quality of their courses is still very good. I often use this to play games and study with my children, which can enhance the affection between them and us, and is very helpful for their future growth and education.
