1. Three-year-old baby is the basic time node of public kindergartens or private kindergartens, and it is recognized by the majority of educational and scientific researchers as the appropriate time. Based on data and scientific judgment, it is more suitable for babies to go to kindergarten. Therefore, it is scientific and reasonable for school-age children to start kindergarten at the age of three. Moreover, before the age of three, children all live and grow up in a small environment at home, so going to kindergarten will help him start a collective life and start social interaction with more children, which is beneficial to his growth.

2. Early education institutions are only extracurricular supplements outside kindergartens. There are many kinds of early education institutions, covering a wide range, including culture and art, and the level of institutions in various fields is also uneven. Parents need to keep their eyes open, carefully screen and choose qualified institutions, and learn more about the experience of other parents, which is helpful to choose early education institutions. It is not advisable to choose too many early education institutions, which will cause too much burden to children. According to children's individual development characteristics and interests, we should choose the corresponding early education category. For example, children especially like painting, and they can choose an early education institution for painting. However, this period of time is still fun as a whole, and it is not suitable for special training and counseling. Otherwise, it will promote the premature development of children and will not help their growth.

In short, the child is over three years old, so it is recommended to go to kindergarten and start a normal collective life. It is enough to choose an early education institution to play a supporting role.
