Is your baby a beginner in the early education class? If so, this phenomenon is normal, and it can also be seen that the baby likes music very much, has a cheerful personality and is very excited to listen to concerts. During this period, about 1.5 to 2 years old is the best time to establish a sense of order, and mothers need special patience and correct guidance. It takes a process for a baby to adapt to a new environment, but although he ran away, it doesn't mean he didn't absorb it. Children have an absorbing mind. In class, parents should actively interact with teachers, and children have strong imitation ability.
