Inoue - I feel mine right at the bottom, under where the placenta is. Feel like it's right on the crease where they slice you for a caesar. That's pretty much the only place I can feel definite kicks. As your uterus grows, the placenta (though it'll still be at the front) should move up some. I've got a fairly good bump on me, but if your bump is still small and neat you might well not feel kicks til a wee bit later on.
