Danielle's cast

In case I haven't filled you in on the story...
Danielle is currently wearing a cast for two more weeks. She started limping about 3 weeks ago, after stumbling as we were walking in to the church nursery. I took her to the doctor, who tried a few days of ibuprofen, then ran some blood tests and xrayed her hips when the limping continued. Danielle had no redness, swelling, bruising, no symptoms other than limping.
She ended up falling again and scraping her right knee about a week later. The next day she woke up during her nap, crying in pain from her scrape, which was not deep and was already scabbed over. Long story short, we got a referral to an pediatric orthopedist and he ended up putting a cast on her. Her leg had been xrayed previously and they couldn't be certain if they were seeing a fracture or normal variations. He determined that she had a hairline fracture below her right knee.
She can walk in the cast but we are not going to the playground or doing water play (or immersion baths) until the cast is off. She's been pretty good about being cooped up more than normal, and you wouldn't know to look at her that she has anything wrong.
