Based on the reviews on this thread, I ordered Sophie for my 4 month old. He loves her
He already likes to chew on the hind foot- usually doing so with a big smile on his face. Unfortunately my four year old also loves Sophie, for the squeaking function

I think Sophie is a good one for us, since DD really needs to chew right now and she is light and soft enough so if DD whacks herself in the face with this toy, it doesn't hurt her, unlike some of her heavier, plastic Sassy toys/teethers.
