My 14month old boy hasn't spoken a word. he just screams constantly. when he's upset or nervous, he twiddles his fingers, bangs his head, or spits. is?

Mgt: I would suggest a hearing and development evaluation. They will be able to best determine the next step.

Needs evaluation: His development needs to be assessed by his pediatrician. He has a speech delay. He should also have his hearing checked. Here are helpful references about developmental and speech delay: http://www.med.umich.edu/yourchild/topics/devdel.htm http://kidshealth.org/en/parents/not-talk.html?ref=search#catcommunication
