Knocked Down but not Knocked Out

Last Saturday Addison fell of Clayton's back and banged her head up pretty good. A blood vessel was broken and a huge instant knot appeared. Clayton was giving her a piggy back ride and Owa jumped out from behind the van. Clayton went down and poor Addi went with him. When I called the "ask a nurse advise line" she suggested I should just bring her in and not take a chance with a head injury. We were at the emergency room for 4 hours and she checked out just fine. The nurse did have me wake her up after she had been sleeping 2 hours to make sure she knew what was going on and who I was. She was so drowsy when I woke her up. She just kept trying to lay down. I kept saying Addi who am I? She kept making funny noises naaam mummm nummm. Then I said, What is our dogs name? She said Luna. I said OK go back to bed!
