As-salaam-alai-kum-wa-rahmatAllah ya taalib-ul-fiqh please advise me after how many years should a child be put in a separate room to sleep and whether the age limit is different for boys and girls. jazakumAllahkhairun wa Rabbana-aatikuma–fahmal-nabiyeen-wa-hifzal-muqarrabeen take care fi amaan Allah
When they reach the age of 10, their bed should be separated but if you feel the necessity before, you should do it earlier.
هكذا فى الفتاوى رد المحتار ، ص:5/ ج:215 ، (باب الاستبراء وغيره من كتاب الكراهية).
There is no difference between the age of boy and girl according to ruling, but however the parents should consider the necessity for the same. If they had any fear, it is alright to make their bed separate.
Allah (Subhana Wa Ta’ala) knows Best
