Her dark spots provide visual stimulation and she squeaks when pressed. She has a soft feel, meant to remind the baby of a mother's skin, and the 100% natural rubber that she's made out of allows her to be super soft and chewy (and totally safe) for baby's sore gums. Plus, she's got a nice, easily identifiable smell of the natural rubber from the Hevea tree that sets her apart from the other toys. Exciting all five senses, combined with uniquely gripable giraffe shape makes Sophie a no-brainer toy for any new baby.
