Hello, My name is Nicole Murphy and I have a group on FB called the "Hirschsprung's Disease Help Group." My icon is the one with the child holding the teddy bear. I am also the author of the book ?Hirschsprung?s Disease ? Solving the Puzzle.? Which also has a FB page. It has proven to be an invaluable resource for parents caring for children with Hirschsprung?s disease. My son Kellen was born with HD in 2003 and suffered multiple bouts of enterocolitis after his pull through operation. You can read our story on my website: http://www.hirschsprungsdiseasehelp.org/ I am currently offering FREE SHIPPING on the book anywhere in the US. Shipping elsewhere is around $15.00 as I do ship overseas. I am so excited about the new group and we have super helpful parents with lots of knowledge! I hope you will find some answers to your questions if you choose to join. Sincerely, Nicole Murphy
