I will say honestly, it's RARE that ANY kitten, feral or spoiled and papered from day ONE, enjoys being held and pet at this age. At 6 months to about a year-and-a-half, they are all over the place with tons of energy and aren't really that calm at all. Think of your kitten now entering its "teenage" years. What teenager likes affection from their parents? Exactly, LOL.
So don't take it personally, as most cats are like this, and many don't like to be held at all. My 3 year old cat enjoys being held for only short bursts of time. My almost-2 year old will gouge my eyes out if I try, but he will tolerate my husband holding him for about 2 minutes. Don't force it, either. Just let her be her and do her thing and keep showing her love and kindness. One day, you'll be mindlessly petting her and she'll be purring and you'll wonder how in the heck that happened.
It will happen. Just be patient.
