Once bub gets bigger, you'll be able to tell exactly where he is. My belly is quite lop-sided in shape, because Calvin lies down my right side - so you can see his body and bum sticking out down my right side (hehe). Sometimes if you poke his feet (on my left), he will kick back at you (still haven't worked out a way to get him to chill out & stop kicking me in the ribs! )
