I have similar experience, too. My ex helper took care of my son for 8 years since his birth. She devoted herself to our family that i didn't need to bother lots of tedious stuffs. However, she has just gone back to the Philippines to get married. My new helper, after 2 weeks, still cannot give me a feeling that i can rely on her. It appears that i have to take care of one more person. I miss my ex-helper.
