2yr old Tantrums. Does your child slap themselves in the face?

My daughter is almost 2 and she doesnt slap herself in the face but she throws herself back on the floor like yours and she bangs her head against the wall sometimes. Its REALLY annoying! Also sometimes when we say NO! she covers her eyes like her boyfriend broke up with her or something. I dont get why is so dramatic, other peoples kids are sooo good at that age!! I personally think its normal. Every child is different and so they all have their own ways to deal with anger and other feelings. My friend has a 2 year old too, and he used to scratch his face when he was mad or upset. He actually stopped, but its just to show you that its only a phase so it should go away.
