Most mothers are sent to kindergarten after they are three years old. Although most parents advocate early education for their children, they are still worried that kindergarten will suffer a lot in the morning. Tingting is the mother of a child who is two years old and nine months old. She said that it is understood that many parents think that it is better to go to kindergarten at the age of three, mainly considering the baby's physical immunity. They believe that if babies under the age of three are sent to school, their immunity is not strong and they are easy to get sick. If the baby is in poor health, it will definitely have a bad influence on his later life. Tingting said that some kindergarten teachers around me also suggested that it is better to send my baby to a three-year-old kindergarten. It is most suitable for experts to go to kindergarten at the age of two and a half. According to the kindergarten director, kindergartens are divided into two types: public kindergartens and private kindergartens. Private kindergartens generally have small classes, middle classes, large classes and large classes, among which large classes are transitional classes from kindergartens to primary schools. According to the relevant regulations of our country, babies aged six and a half to seven can go to primary school. According to this age, it is more appropriate for the baby to start kindergarten at the age of two and a half. In fact, considering the following three factors, it is most appropriate for a baby to go to kindergarten at the age of two and a half: the baby's physical immunity is enhanced, the baby's independent ability has emerged after a period of training, and the baby's intelligence, such as comprehension and verbal expression, has reached a certain level. At the same time, because there is a great demand for babies over 2 years old to explore actively, the non-family exploration environment provided by kindergartens can usually meet the baby's exploration heart scientifically and reasonably. Warm reminder that anxiety in entering the park will reduce immunity. According to a large number of studies, the separation of parents and children and the anxiety caused by the new environment will make children's immunity decline when they first enter the park. So many new babies have symptoms such as physical discomfort, cold, fever and cough. After entering the kindergarten, the baby needs to re-recognize and adapt to the new environment, and the baby's schedule has also changed, so some parents think that it is more appropriate for the baby to go to kindergarten at the age of three, because the baby's immunity has been enhanced to a certain extent. In fact, just as babies can receive early education to grow up, parents can enhance their babies' immunity through other channels, so that they can have a stronger body and start kindergarten at the age of two and a half. There are many private kindergartens now, and babies under two and a half years old are taken in order. Here, parents are advised not to let their babies go to school in advance. If family conditions do not allow, parents should also pay attention to cultivating their baby's intelligence such as understanding, imagination and creativity in daily life.
