Anyone have a child diagnosed with a mild form or celebral palsy?

my son is 17 months old and we recently saw a neuorolgist because he is not walking yet and his right hand does not have much dexterity. the doctor said he most likely has a mild form of celebral palsy (i cant remember what he called it exactly) but he needs a mri to be sure. i am very scared because not only does he need to be put asleep for the mri, but he will likely be facing a lifetime of physical therapy. he is a very smart boy, he just cant do things as well as other kids his age. has anyone else had this early diagnosis and if so, what was the outcome and how is your child doing now?
