Hi, I am new to this site and I am having issues with my 4 yr old son. In the past month or two I have noticed a major change in him. For the most part he is a good and loving boy but lately he has started having "tantrums" as I like to call them. It began that he started to come get into bed with me at night and this lasted for about a week. Then came the I do not want to go to school, and we still argue about that. He only goes to school 3 full days a week and the other two days he stays with his grandmother. Then came the tantrums, anytime he is told no or does not get what he wants he loses control of himself. Ethan throws things, hits things, throws himself on the floor, screams, and the newest addition is he started to spit. He has also been showing alot of aggression towards his sister. He started punching, pinching, and kicking her. You name it he does it to her. I try to punish him for this by putting him in a time out, when this happens he loses control of himself and the tantrum begins. I am not sure what to do. I try not to spank and we have used a 3 strikes rule, meaning if you get 3 strikes for doing something wrong you lose something fun. This worked in the begining but is no longer effective. I also have problems at bedtime with him, he refuses to go to bed when it is bedtime, he disrupts his sister from going to sleep. Any advice here would be wonderful. I am at wits end!!
