Hi everyone. I am not a parent but i am here for my nephew who is like a child to me. He is 3 years old, 4 in august. His speech is not where it should be, there are a few letter sounds that he cant say. He doesnt know his A,B,C's and can't count past 4. His parents arent really working with him to teach him this stuff but this isnt the main reason for the post. Im posting because he has within the last few months been saying some things that have been worrying myself and his sister (who is 21 and has a 15month old who has far exceeded his learning and speech). Ive noticed he is rough with the animals in the house, they got a new puppy and despite the "be gentle" and everything he still would pull the dogs tail until it whimpered and ran off, then he would laugh. His sister was wrestling with her boyfriend and their daughter on the floor and he asked her if they were having sex. At least twice he has been caught saying frightening things. Once with me while watching the Chipmunks movie he whispered "Im gonna stab them and kill them and then theyll be dead" He said that twice, I told him that wasnt nice to say and he continued watching the movie. A few months later his mom spanked him for trying to climb on the couch and he tried to choke her. Shortly after he was at his sisters and he had told her "When i get older im gonna stab you, chop you up into pieces, and then you'll be dead" and this worried her. I understand sometimes kids say things they dont understand but he just has this look on his face like he knows what it means. Is this something that some kids go through or is this some sort of gateway into a severe behavioral problem? Im really at a loss here and im so worried about him. Please help.
