Isent a question to this website called AllExperts to see what they said about Jack. Here is what I got.
Subject: Speech delay or mountain out of molehill?
Volunteer Expert: Tim Runner
My 15 month old son has no words as of yet. I started sign language with
him at 12 months and he currently has about 50+ signs. His hearing is
100% and he communicates with me very well using either his signs or
gestures. He will mimic me when I encourage him to say mama, baba, dada.
All other attempts to get him to mimic are ignored or he signs back at me.
He has been evaluated by Early On and they found that he scores higher than
age level in all areas except speech. His signs known and used actually put
him higher than age level for language. We are currently waiting (4 weeks)
for a call from the speech therapist to find out IF she wants to evaluate him.
My question is should I be worried?? I have heard everything. He will grow
out of it, Einstein didn't talk until he was 4, you are creating the problem by
letting him sign instead of speak and more.
He seems to focus so hard on my mouth and WANT to mimic, but just can't.
It sounds to me that your son has a significant delay in speech and needs professional help right away. I'm glad that you are having your son assessed by a speech and language professional. Many medical insurance programs will pay for this. If your plan does not, contact the school in your area that he will be attending when he gets older and seek their help. They can tell you what government agency to contact for help.
