Did she come from a pet store in Singapore? From what I've heard and read over the years, that's a pretty dismal place to come from. If you've only had her 3 months, then she's doing pretty well behavior wise. The mantra you need to remember is "time and patience." As noted above, chins are not cuddly, sit on your lap kinda animals. For one thing, they overheat easily when being mauled by their owners. They are more of a watching pet, where you interact on their terms, not yours.
