now your being a step mom getting to the root of the problem hang in there take him out for ice cream for talking to you reward the good and it will keep coming. if he knows he is safe opening up to you he will continue. give him possibilities that he can try to solve the problem on his own. with your guidnance but by himself. now you are being a good step mom. keep it up
he needs to be included somewhere and you need to be the one to include him if you go to the store invite him. be his friend. if you want to take him to the park do it. give him an escape for his emotions and make him feel included with you.
he is trying to learn how to make friends and doest know how you need to take the lead show him how you are going to make him your friend and he can follow you. next time he acts out instead of punishing him ask him what happened that day and let hiim unload on you. don't criticize. just listen and give suggestions. you and dad need to pay more attention to him if you two go out invite him along. if dad goes to the store have dad invite him. make him feel he belongs somewhere. if he cant do it at school he needs to do it at home. YOu are getting somewhere with him now. keep going. hang in there.
