I become their voice. The majority of 2 year olds bite because they are frustrated or angry over something, but do not have the verbal skills to express their feelings. I've seen this time and time again when I was working in the 2 year old room of a daycare, I've seen it in my own kids. IF they bit I would sternly tell them NO BITE! and move them to another area. With my kids I might also flick their cheek while telling them no bite.
Another idea is to watch your 2 year old. There are usually warning signs that they're getting upset over something. My daughter would get flat pissed at her shape sorter because the star piece would NOT fit into the triangle hole. I would watch her try and try and when she started trying to beat the piece in, or just beat on the toy itself I'd look right at her and say: I'm SO MAD! This star WILL NOT fit here! as I was getting down on the floor next to her.
