Ex-pat family looking for second helper

My wife and I are expats (American and Thai) living in the mid-levels and we both have lived in HK for more than 10+ years.  We have two young children (a 4 year old boy and a 21 month old girl).  We currently have 2 helpers and a part time cook. One of our helpers (the cousin of our other helper) is returning home for family reasons and we are looking to replace her.  This role will primarily focus on taking care of our 4 year old boy and thus we are looking for someone who loves to laugh and play, is physically active and can be both loving and firm at the same time.

Please note the role will require you to share a room with our other helper and have your day off on this Saturday. If you are open to this we would love to chat with you as your background looks great.  Thanks!!
