In fact, for whatever reason, daughters are called sons. When the child is about 3 years old, parents had better change their ideas. The child is about 3 years old and has begun to have gender awareness. If parents always call girls their sons, they will feel vague about their gender, like to imitate boys' toilet movements and dressing up, and even gradually tend to be boys, without girls' femininity.
After the children enter school, parents call themselves "sons" in front of other children, which will also hurt the children's face quietly, make them feel embarrassed and even be laughed at by other children.
