Key words I want to raise my children "violent free." Toddler's by nature are "violent" but they do stop it with constant intervention. It sounds like you just leave them to their own devices so of course your older DD would hit/pinch etc the younger one. If you want the behavior to stop you can't leave them unsupervised. Separate them and their toys if you can't keep an eye on the older one. If she hits her sister redirect her immediately.
