Babysitter/Nanny Needed For 1 Child In Vienna

Experienced babysitter/nanny wanted for 17-year-old boy with special needs on Saturday/Sunday afternoon/early evening, approx.. 4-8p, and after school during the week in the afternoon/early evening (after-school hours will vary depending on my son s schedule). My son is non-verbal, has a seizure disorder, is not toilet trained (will need to be taken to the bathroom and changed often), has cognitive and developmental disabilities but no physical disabilities, and has many autistic behaviors. He uses an iPad, sign language (ASL) and word approximations to communicate. Experience working with a child with special needs required.
