Suggest Remedy For Problem In Swallowing Saliva In 9 Month Old

Good day, my name is Gerhard Swanepoel and my grandchild was diagnosed with Krabbe Disease. In South Africa it seems that a verfew doctors are aware of the condition though we have Dr Lippert, an pediadric neurologist with a number of patients. My question is on salivation as she is now 9 months old and start with serious problems not be able to swallow the saliva that builds up in the throught. IS there a way to prevent the saliva from building up - we are in the process of bying a suction machine. Can one dry the mouth - if yes how and what would the freuquency be to so so? I am of the opinion that this built up of saliva causes nauseousness
