Western/French Family looking for a helper

We are a french family living in Ho Chung New Village (Sai Kung Area) looking for a new helper as our current who will go back to Philippines at the end of her contract.
We have 2 kids, one lovely girl of 2 years old and one boy of 4 years old.
We need someone who can take care of kids, they are the number one priority.
The other task will be housekeeping and cooking.
We usually do our groceries ourself but occasionally it will be needed to be done by the helper but it will be occasional.
