These babies respond like little kids. My rule with my kids was to choose my battles. If I knew something was going to set them off I just didn't alow them to get in that situation.
Example: my son was a very picky eater. Between 1 and 2 years old when he should have been developing his taste buds, he was having really high fevers from inner ear infections. (He needed tubes in his ears but the military hospital on the base I was stationed kept putting it off). His father constantly yelled at him while we were eating and he developed a phobia about food.
The solution was to feed both kids before their dad got home. I chose foods for the meal that he could also pick from.
They always got into it at the skating rink. One scatted better than the other and the lesser was always being instructed how to skate so it was not fun. The solution was to alternate Saturdays.
If he bites you in a situation, don't get in that situation. If it means not touching him, go back to scared bird training.
