And he finds it hysterical when i say "NO." very sternly. If i yell or pull him away too suddenly he gets very scared and cries. He has also started hitting our cat and throwing toys at all of us. Sometimes hard ones right in the face. i got a book on no hitting but it hasn't stopped and sometimes he seems to almost seems to think it's a game and wants me to catch him or wants to hit me for fun! He has been giving so many hugs and kisses and was so gentle before but now this. I don't know what to do to get him to stop. Help!
