The advice I found most helpful at the time of diagnosis is, "Take one day at a time!" Also, as much as the children resemble each other and mirror so many of the mannerisms, they are still very individual. Do not compare your child to others and assume they will take the same path. There are no absolutes other than it is still a terminal disorder. All of the other variables are just that, variables. This means your child may or may not see that symptom. Your child may live much longer than another, or suffer at an earlier age. Do you best to raise and see your child as themselves and not the illness.
