Chinese family with 2 kids (3 years girl and 7 months boy)

Most of time is me and 2 kids. Sometimes my parents and my grandpa will come to live but my mom will do most of the work. We live in Tung Chung. I have work but most of time i stay at home to send and get my daughter to and from kindergarten nearby. and i would like to cook. I treat my helper like my sister but she has to go back to take care of her own 3 kids.
