Discipline means teaching, not strictly punishment. It's seldom if ever necessary to slap a hand or a butt if you study what's developmentally normal at different ages, and work with that. If there are things that are truly off-limits for a toddler who is at the age where she MUST explore and manipulate, then those things are best placed or locked out of her reach. She WILL outgrow this stage (which I've heard called such terms as "Fill and Dump") and enter some other exploratory stage.
I don't think it's ultimately advantageous to discourage a child's natural curiosity. It's far better to give alternative outlets that let her motor skills, eye-hand development, and visual discrimination grow. For example, at around a year and a half, kids MUST throw, early and often. They're developing essential coordination by repeatedly throwing, dropping, and whacking at things with an overhand motion. You will thrill them by giving them soft, throwable objects and participate in target practice – a basket, box, or hula hoop on the floor, a soft pillow to whap with a styrofoam stick. Then precious objects are less likely to be targets, and the child will be less frustrated when you redirect them away from things they shouldn't whack.
So provide at least one shelf, and at least one drawer, full of toys that can be repeatedly removed and replaced. My grandson had a drawer in the kitchen that he could raid for unbreakable bowls, spoons, pans and cups, so he could "participate" while his mom was fixing meals. It was a brilliant solution. He could be directed to his special drawer anytime he started exploring the no-no cabinets.
