HK/ Korean family looking for a kind helper

I’m looking for live in helper to take care of my 3 year old boy mainly plus household chores! He goes to school in the morning so main duties is to look after him and give him food when he’s back. Grandma pick him up from school and will stay for a few hrs until I return from work. My current helper needs to return home as her son is sick. We respect our helper and hope to find someone that will love our kid and stay long term.
