How do you find nanny? Through nanny service agent or referral?

I prefer getting referrals, it makes me feel safer and more comfortable. I got a nanny for my son when I went back to work. Her job was to do everything for the baby, nothing for my home. I had a second helper to do that. Nannies I feel should focus just on the baby. This is a good article you can read up on for more info: http://sg.theasianparent.com/find-a-babysitter-in-singapore/
