Looking for helpers for 2 kids, have co-worker

Let me cut it short by telling /asking you about my family situation 1) I have 2 kids, a 5yrs old boy and 1.5yr old girl. So the 1.5yrs old girl needs extra care. Do you have any experience in taking care of children? 2) do you mind to work with co-worker? Do you have any experience in it? I already have one helper with me now 3) as you know the place in HK is small, do you mind to stay in the same room with my kids? Will be a bunk bed, you will stay in a lower bed 4)In terms of holiday, do you mind to take Saturday off?
