Babysitter - Full-time / Part-time

We have a cockapoo she is 5. Very active. Very friendly once she gets to know you. Until then she may bark or hide. I am a therapist so my schedule will vary from day to day. I need someone to come late afternoon/evenings 3pm-9 p.m. I need someone reliable to look after my 1-month-old. Feedings, diaper changes required. Nj transit bus stop is near by. We have a drive way
