First is that she needs to know how to cook. My husband is very particular when it comes to cooking, so that is a requirement for our yaya. Second is that she needs to have an experience in taking care of babies. She also needs to be at least 20-35 years of age. Yayas who are older tend to complain more about doing household chores. The process is that my husband and I both do the interview, then we talk about the rate. Standard rate in Iloilo is 3k, with only 2 days leave per month.
I'd say, honest and passionate with kids. Secondary are: industrious and good cook.
