K.,
It has already been said, but I'll also say that Sign Language is a big help. It has helped my family in many ways. My daughter is a late developer in her speech and it has helped her to communicate. There is almost nothing more stressing than not being able to communicate with your child. Not only has it helped my daughter, but when my mother or I loose our voice (which is not all that often), we use sign language to help our voices heal faster. The only problem is that you have to have someone that understands it. I am still looking into getting my interpretation degree and I highly recommend Sign Language for anyone. Good Luck and hope this helps you.
God Bless
