hi bakaholic,
I recommend Mary Rauff, she was the one who delivered for me. She & PC Wong works as a team, they cover each other when one goes on leave.
To those hunting for a maid, my advise is to start early. Just want to share my experience. I wanted my maid to arrive just a week before I gave birth. I chose one brand new one at the end of Oct, supposed to arrive 1st week of Dec, guess what? She ran away at the airport. Imagine how I panic! Just the week before I delivered, went back to the agency to choose another maid. This time I told them I need the maid urgently. Eventually my new maid arrived at the end of Dec, after 3 weeks of my confinement. Luckily hubby took 1 week of leave. My mother and I struggled on our own for 2 weeks. Very tiring indeed. So pls dun wait too long to get your maid.
