Yes, she's pulled one muscle and strained another, in bed. I didn't have anything to do with the former -- she describes it as an accident which occured while reading. I suggested she eased herself gently into reading, perhaps starting out by looking at pictures until she was properly warmed up. She'll try. The other muscle was my fault -- I'm obviously working her too hard. Again, some sort of training regimen seems to be in order.
