Hopewell, looking for a babysitter - RG10 Waltham st lawrence

I am looking for a babysitter to work fairly regular weekends (not every weekend, but most) for the family that I work for.

They have 2 children who are 3 years old (little boy) and 6 years old (little girl), both wonderful, very well-behaved children.

They live in Fulham but they have a house in the country in Waltham St Lawrence (nr reading). They spend near enough every weekend at the country house and they would like to have a babysitter around to help them out when they are there.

They are a genuinely lovely family and very easy to be around. They just want someone to be around to help with the children and be on hand of they want to go out in the evenings, etc.

They need someone for approx 80% of the weekends throughout the summer and approx 60% into the winter.

If you can only do the summer weekends that would be fine but I would ideally like to find someone that will be able to work with the family going forward as well.
