According to the Regulations on Kindergarten Work of the Ministry of Education, kindergartens are institutions that provide education and care for children over 3 years old. Their classes are generally divided into small classes of 3-4 years old, middle classes of 4-5 years old and large classes of 5-6 years old. Children under the age of 3 can take care of them, and it is not advisable to enter the park too early. At present, public kindergartens generally require children to be at least 3 years old.

Private kindergartens usually do not require age, and some may require more than two and a half years old, so generally speaking, it is more appropriate for babies to go to kindergarten at the age of three or four.
