When I brought my little girls home, they wouldn't eat very well at first either.
I made some rice baby pablumn, and mixed a little honey into it and put it on my finger. They would lick it off my fingers, I also hand fed them some broiled chicken breast ( no skin or fat) and make sure it is cool. I also left a little kibble down for them at all times. I still leave the kibble down and every so often I hear a crunch. I now make home cooked food for them, but I still leave a little high quality kibble down for them to munch on during the course of the day.
