Chinese family looking for a baby care helper

Hello, we are 2 Chinese young parents with 1 baby, the baby boy is 2.5 months old, healthy and easy. We are hiring a full time helper to live in with us. We can provide a separate sleeping room and a separate shower&toilet room for this helper in HK. We expect this helper to take care of the baby boy with an elder, because the boy’s parents need to go to work on week days. Both parents can speak fluent English, Chinese and Cantonese. We are open minded and easy to communicate. Baby caring is the main focus, plus grocery and housekeeping. Cooking is associational as both parents dine out often.
