I wanted to say my son has a chromosomal deletion which has caused him to have severe cognitive impairment.  FYI:  The NR work has helped him tremendously.  No conventional therapies have made him advance as NR. I can’t even imagine where my son would be without this therapy. We have been doing NR for 3 years and going strong!!  I’ll take this opportunity to thank Bette for her sincere devotion to my child’s progress! I strongly recommend this intervention. Jane g
