first maid was a yanyan, she was Ok to take care of the new born. when my daugther getting older, i found the yanyan had very little communication with my daughter. in day time, the yanyan cannot read the book for her or even sing together.
after yanyan finished her contract, i switch to bunbun. when i access the webcam, i can see the bunbun read the book or sing or play games with my daughter. and my daughter's teacher told me my daughter improved a lot with her speaking skills in the last few months.
people always ask bunbun or yanyan? it's really depends on the luck. there are many good bunbun and yanyan, also some are very bad.
