Chinese family looking for a domestic helper

We are a Hong Kong family of four looking for a kind and responsible domestic helper. We have a working couple with a newborn (coming in Feb 2018), an elderly (67 yr, stay over during weekdays) and a tame cat.

Contract starts in mid / late Dec 2017

Main job duties:
1. Take care of the newborn
2. Do the routine housework (cleaning, washing, cooking, grocery shopping etc.)
3. Take care of the elderly (The elderly can perfectly take care of herself at home, but the helper has to accompany her when she goes out and carry a wheelchair in case she cannot walk long)

Remarks:
- Share bedroom with the elderly when she stay over (bunk bed)
- Sunday off (negotiable)

*Prefer helpers who understand / speak basic Cantonese, and those who are already in HK and finished contract.
