My son is 4 1/2 and his behavior started at 3. We have talked to doctors and changed doctors and they don't want to do anything since he is so young. He goes to head start and that's where most of his behavior problems. The teachers even filled out adhd papers for the Dr. He has left the house while everyone is sleeping trying to drive his dad's truck, he has did this 3 times even with chain locks on the main doors. He has extreme tantrums, sleeps horribly( sleep apnea and tonsils removed now awaiting the new results), lies, deliberately does what I told him no to, so so hyper, impulse control problems, and so much more. Today was my last straw he told his teachers to shut the f up that he was going to kill them all, pushed a teacher down and hit her in the privates. We have him in therapy to we just don't know what to do. Please any advice would be so helpful and I'm sorry this was so long. He is such a sweet, kind, loving little boy but anger consumes him some.
