Prayer for my child

Please can you pray for my child that is living with family , I sent him away because he was not behaving and was doing very bad at school , joining the wrong company , smoking and doing all the wrong things.

I sent him away so that he will have a change of place and change his life.

He is still not behaving ,doing things to upset the people he is living with, I do not want to bring him back home .

Please can you pray for him to change his life and obey the people that he is living with . he must study and be a good child, do not do the wrong things ,go on the right path.
