My son is very girly, he talks very coquettishly, he always likes to repeat words, he bounces around from time to time when he walks, and he calls each other "sister" to the girls around him?

First of all, check the environment in which he grew up. Are there more girls around him, or his parents like to dress him up as a girl for a period of time, which makes him have certain errors in his understanding of gender; secondly, find someone to compare his horoscopes. Take a look at his name. Maybe there is an imbalance of yin and yang in the name, which may also cause this situation; thirdly, you can go to the hospital for a test to see if there are too many hormonal foods in the diet
