Is what a 3-year-old child is experiencing, namely food refusal and consuming only milk via bottle-feeding, an 'ayn (evil eye)? And should he be presented to a reciter of the Quran?

If a child is afflicted by the evil eye, the cure lies in supplication and seeking refuge in Allah, protecting him with morning and evening awrad (litanies) and adhkar (remembrances), and with ruqyah shar'iyyah (Islamic exorcism) by reciting Al-Fatiha, Ayatul-Kursi, Al-Ikhlas, the last two verses of Al-Baqarah, and the two Mu'awwidhatayn (Al-Falaq and An-Nas). His father or a righteous person can perform ruqyah for him, while being cautious of soothsayers and charlatans. If the person who cast the evil eye is known, he should be asked to wash his limbs in a vessel, then the water should be poured over the child. Furthermore, the home must be cleansed of sins that attract devils and remove Allah's protection.
