Helper Foe American Chinese Family

We are a family of four American Chinese couple with 2 daughters (2 and 4 year olds). I’m looking for a helper mainly to take care of my kids and house duties. She is willing to share work and room with my another helper who is the main cook for the family. I hope to find someone who has a big heart and a lot of patience for my kids. Salary to be negotiated based on profile and experience.
