Within a week of her last Dr. visit. Chuck is hobbling around the house with either a cane or one crutch.
Since there's snow, she's still using two crutches outside, and two in the halls at school.
And it is absolutly hilarious watching her bring her brother down the stairs. She sits on her bum at the top, and puts him in her lap, and the two of them "tobbogan" down together.
