Good! no attacks. Gr8 to hear an update.
Patience is the key---just keep rewarding good behavior and giving her attention with lots of cheek, head and back scratches or spots she really enjoys for as long as she wants or can tolerate. Some cats never are lap cats, but just like to be beside or near you. Tell her what a good girl she is and think positive thoughts. It may take Cookie a while, but one day she may surprise you and decide she wants to give you a head butt=hug or touch noses=kiss.
