My son is 5 years old. He is having a slight adjustment problem (he was home with mom and now is in kindergarten--he cried the first week but is now trying to deal with reality)He is generally a moody person,but my major concern is that when he is playing or concentrating and you call his name or the phone rings, he gets "startled." He used to cry when he was younger (he has always "startled easily") but now he gets VERY angry and "goes off" verbally. He is also manipulative when corrected ""ie. you hate me," "you don't like me," bla bla bla.) Any suggestions? Thanks!
