Hi. My son has mild CP and also had trouble talking. He is now 6 years old but we just had to keep working with him on sounds. The speech therapist will help a lot. Another thing we tried also which was recommended because since my son couldn't talk, he would get real frustrated....teach sign language!! Just a little info too, my son talked, then stopped, then we had to teach him again when he was 3 and now he can say lots of things and even quit getting speech therapy when he was 5.
Good luck...it does take lots of patience but like I said, the therapist will help lots as well.
