This is what you call superior flexibility.

Oliver at five months. He can roll from back to front and front to back, a lot of the times he rolls across the floor unless there is something in his way.  He likes to chew on things and grabs anything he can find to put in his mouth (including his toes). He laughs and talks a lot, he knows who mom is and always wants to be held.  Much to the disappointment of his parents he hates his pacifier and screams when it's put in his mouth.
