Very typical. Most of my children and sisters children did the pinching and scratching. We collectively figured out that it is a response they are trying to trigger. Once you react they know that this is a way to get a response. I would take my childs hand and stroke it down her face and say soft. They take hers to mine and say soft. Try not to show an emotion when she pinches you. The more you react the more exciting if you will it will get to the child. Sometimes mine would pinch then cry. Because she knew she hurt me. This stage will pass. Don't be surprised if she pinches others too. Mine were running at 10 months and would get a hold of her brother and pinch away. Talk about getting a good response. My son would have to contain himself and say no pinch to his little sister and walk away. This will pass.
