DD1 has always been spirited. She is full of energy, confident and generally quite happy. She eats and sleeps well and has been at nursery since she was 11 months old.
Fast forward a year or so and she has turned into a monster. She hurts other children at nursery - biting, scratching, kicking, pinching, kicking. We've had complaints from parents at nursery.
We went to a music class this morning and she pulled a little boy's hair, knocked over another baby and whacked a parent with a shaker. 
We removed her from the situation and apologised.
Yesterday we went out for a picnic and she ran some distance away. We called her back and she ran further. We chased after her and she sped up. We strapped her into her buggy and she rocked back and forth so violently that the buggy moved and hurt our friend.
She pretty much does the opposite of what we ask her to or she will shout "NO" or " I DON'T CARE" at even the most simple request.
It's driving me nuts. I feel like I'm constantly moaning at her to do or not to do something. I've tried focusing on the positive but when she or others are in danger, it's difficult to do. Star charts don't seem to have any effect. It's draining but mainly it's upsetting that she hurts others. It's putting me off doing anything with her. It seems entirely unprovoked. She could be walking past someone in the street and lash out.
We have had another baby recently and I know this can cause bad behaviour. Does this sound like normal toddler behaviour or should I be worried?

Defiant, aggressive 2.10 DD, at my wit's end!

I don't know what to advise, but we're in a similar situation with our 3.4 yo son (I just posted something similar, I'm losing the plot!).
He isn't aggressive towards other kids but has become completely stubborn and rebellious. Like your DD, he ignores us when we tell him to stop doing something. Sometimes he has epic meltdowns, so much that we have to grab/restrain him until he calms down. We don't use the pram much lately but he used to do what your DD does (rocking his head violently, he hurt himself with the buggy frame a couple of times!)...
Sorry, I can't help much, but just wanted to say we're going through the same... It's exhausting.
