inxin can speak later than other children. I remember that when Xinxin first called "dad", the whole family was excited for a long time, and the original worries and doubts in my heart also disappeared with Xinxin's "dad". The child is always quiet and well-behaved, and doesn't cry much. At first the parents just thought the child was shy, but until Xinxin was three years old, she would just be called "dad". The parents decided to take Xinxin to the hospital for an examination.
