Jimmy has been doing this recently too. He is 6 months old now and started when he started teething his canines.
I think he is getting agitated or showing aggression to the toy in his own little world but he doesn't get mad at me or anything. He will growl for a second but I don't think it's at me but his built up "Yippie! I'm gonna get you" when I pull him from his toy. |
