My stepson is 4 and a half years old. Just started pre-k. He has been pushing other children at school. He will walk by his little sister and just push her down, smile and walk away. He steals at daycare and school now. He lies about it. He sneaks things that he knows he should not at home and other places. He is aware that what he is doing is wrong it seems but he has no fear of the consequense. You talk to him about his misbehavior when he does something wrong and it's like talking to a brick wall. His eyes glaze over and he just looks at you with this blank stare.He will say he understands but you know he just says it. He has no control over his impulsives it seems. He has had this behavior for years and it's only getting worse. He sneaks into the kitchen, steals food from the cuboards or wher ever he can get into to get it. We have to lock up everything. He will eat frozen meals from the freezer. He climbs on top of the refrigerater to get into cereal that we have hidden. He will get the food and go into his room, make a huge mess and most of the time he tries to hide it but sometimes he does not care to. He has become very defiant to me lately. Say's no when you ask him to do anything, constantly whines and cries over the simpliest things. He does these things every single day. He will get punished and continue to do them. It's like he has no real concept of right and wrong and no fear of getting in trouble. This has gone on for years and lately is only getting worse. I don't know what else to do. Does anyone have any ideas or suggestions of possible disorders he may have.
