I am so glad we are not the only ones. Our little guy is almost 9 weeks old and he has been doing really good. Today was the first time we had to spend several hours away from him (coming back to give him a potty break in between). When we got home for the evening, he seemed very aggressive. He was biting at anything that was close to him, ie: my leg, arm, toes, fingers anything! I can't tell if he is just plain being mean or if he is just playing hard. I tried to put him on his back, but he never would give in. I know some people don't like to put them on their backs, but I didn't know what else to do.
