I am a very concerned mother, my son is 4 years old and he is the youngest of 9 children (he is also a twin). Last night he came to me and handed me his sisters hamster that was dead and bleeding from the mouth. I asked him what happened and he said he killed it by throwing it but didnt want to talk about it. I asked him if he cared that he hurt his sisters feelings and he said no. Then tonight he told me he did it cause he wanted a hamster too and I wouldnt listen to him when he told me so. He was crying and he did apologize to his sister tonight. He is a little aggressive but ive always chalked it up to hes just being a boy. He likes to rough house with his puppies but then if they bite him on the ear he gets mad and hits them. I have been working 6 days and week 12 hours a day and not able to give him the attention he is use to. I am very worried I dont know if I should take him for a mental health assessment. any advice you could give me would be wonderful. thank you for your time. PS I also asked him if he understood that when you kill something it is gone forever and he said no.
