Hi M. -
My son could only say 2 words at 18 months. My pediatrician recommended an evaluation by ECI. This is a self referral service through the county. You can just call them and they will talk to you about and see if he needs an eval. They determined that my son could use some speech therapy, but also said he may just be deveoping in other areas first or just taking things in. He had speech 2Xmonth for 6 months. I honestly don't think they helped that much, but they gave me some good tips on what to do at home to help. I personally think he just developed late. He is now 2 1/2 and we have conversations with him! After he turned two he started talking...a lot!!
Also, we found a video he LOVED called Baby Babble. He wanted to watch it over and over every day. It encourages speech development and I really think that helped. Good Luck!
Please let me know if you have and questions and I'll try to help. Good Luck!
