Soft toys are a hit with girls because they are so cute and cuddly. Soft toys can also be comforting. Luckily you can find these in Star Wars characters so girls don't have to miss out.
The Underground Toys range has some excellent Talking Plush Star Wars toys. The Chewbacca and R2D2 are the cutest I think and are good choice for a girl. Cuteness is important with soft toys. So your daughter will be more excited if the soft toy has a cute look. Cute toys are also more cuddly.
The Yoda Pillow Plush is the cutest Yoda soft toy I could find and another good idea for a gift.
It can also be helpful to find out what characters your daughter loves. I really liked R2D2 and Yoda as a child. I would have loved a R2D2 or Yoda soft toy but they weren't available when I was a child unfortunately.
