Salina, is looking for a part time nanny in Great north way NW4

I am looking for trustworthy babysitter who is Ofsted registered, first aid trained, I need the babysitter mostly between 6.30 am till 4:30pm from 30th depending on my shifts. I will inform about the shifts in advance. Once his school starts the needs will differ. As he will be in the full day school. So it will before school and then sometimes after-school, this too would be informed in advance.
