Family of 3 looks for a helper

Regular routine: Drop off and pick up our 3 years old boy to/from school. School is nearby and ideally the candidate can ride a bicycle. Cleaning and house tasks when our son is in school. Groceries are usually ordered online and we eat at home during school days. We have a bedroom and bathroom for the helper. We are a French and HK Chinese family where English is the language we use at home. We offer SGD$800/month.
