What is the relationship between jinn and children, and does a jinn ask to see a female child?

One should not assert with certainty that the mother is afflicted by jinn possession unless there is absolute conviction. If confirmed, she must be treated with legitimate ruqyah, such as Ayat al-Kursi and the al-Mu'awwidhat (Surahs al-Falaq and al-Nas). She should also frequently remember Allah and seek refuge in Him. As for the jinn's relationship with children, we have no knowledge regarding it. Seeking refuge in Allah is the solution.
