I was wondering how severe most of these cases are where celation is used. My eight year old cousin has very little speaking capabilities and when he does talk it is usually something that he has previously heard (esp, movies) or read. I was just wondering if this method works better on a certain degree of the disorder or if it would work for any child with this problem. Also, I heard something about vitamin therapy about a year ago, but since then, nothing. Can anyone tell me what's involved in the vitamin therapy option? Is going through the celation painful for the child? How long do children have to go through these treatments before it is determined that they are finished? Any information would be appreciated. Thanks.
