I have a tiny little Yorkie too, my Gypsy weighs 2.2 lbs. I would NEVER consider keeping her in a bird cage to 'keep her safe', or try to make her live off of baby food instead of dog food. I hope that once she made it into the spotlight someone was able to give her an education on the proper care of a dog.
I adore my Yorkie, and treat her like the little princess of dogs, however she IS a dog and needs the care and nutrition that any other dog needs.
Sad to hear this little guy passed away.
