Over the weekend my 7 month old decided to bite my legs, arms, tummy, everything! He literally attacks me like a monster or vampire. He's not angry or anything, he just attacks for...fun?

Please tell me he's not the only one. It's very strange because if I try to push him away he finds a new spot to bite! Is that normal? He doesn't laugh about it either. He's dead serious about biting me.

This!! The shark is him and the hand is me pushing his face away.
