Babysitter Needed

My son is within autistic spectrum, non verbal. I usually need help with him from 12:00 till 21:00, pick him up from day care, feed at home, bring him to have a nap and bring him to evening ABA classes. At 18 I can pick him up by myself so nanny can have time for food prep and feed him at 19, prepare child for sleep and finish the day at 21:00. I need help Monday to Friday as Im working on business days. Occasionally I might need help on weekends on optional hours but it can be under discussion with nanny and weekend time depends on her as it is not mandatory.
