aggressive child

my little girl has been very aggressive lately with pinching and slapping and kicking. anyone else's doing this? I read it is because her emotional desires have developed faster than her being able to communicate but she talks extremely well and tells me when she has to poop and hungry and wants snacks. but she doesn't say too many full sentences. she also gets mad when I make dinner or do dishes she comes and pushes me away from the stove or sink and pinches me if I ignore her. but then she is so sweet sometimes. I say to my bf that she is the sweetest demon lol
