I think Sierra is having a little trouble with depth perception or maybe just understanding how far objects will swing. Sunday she got whacked with a hockey stick on the arm when the boys were playing street hockey. Tuesday she took a baseball bat to the eye while the boys were playing street hockey. We only have two hockey sticks so the boys improvise with a baseball bat and tennis rackets. The first picture was taken yesterday. The second one was taken today. It feels better as it looks worse. It's not nearly as bad as the ones that Sean has had and her glasses help hide it a bit.
