I am the very proud parent of two (normally) well behaved children (4 year old son and 1.75 year old daughter) who is new to this site. Now that we have that out of the way i really need assistance with my son. Our son is displaying extreme agression with his preschool teachers daycare providers to the point my mom is now watching him. Our most recent incidents include a two day trial with a sitter who comfronted him for a minor incident and he spit in her face. He was required to leave a preschool due to similar behavior with others. The common denominator seems to be when he is being redirected, corrected, or made to do something he does not want to do (finish his dinner, sit quietly, stop hitting, etc...) We have sought professional assistance only to realize we really had to instigate any of these behaviors out so the person could witness his behavior. We have read Dr Greene's "explosive child" recently and are instilling this in our daily routine with minor success. Our at home incidents are usually much less extreme than those at other locations and this causes extreme fear of even attempting another facility. The fear is we are adding fuel to the fire by introducing another element. I understand that somethings are normal in child developement, but his actions to others seem so angry. As far as his relationship with his sister, they get along fine if she does not knock down his towers he builds with blocks. We can handle the homefront, but we both need to work. My mother watching him can only be temporary. Thanks for reading.
