Broken Arm Saga - lite

Chance broke his arm in late April.  All it took was a tumble on the sidewalk.  I told him to run back to the park to grab his forgotten sand bucket....yeesh Mommy guilt.  After 5 weeks, Chance's arm was deemed fit enough to have his cast removed.  He wore a splint for 4 weeks and then had a follow up x-ray and the doctor said things were looking really good.  Now it's 3 weeks later and so far he hasn't complained of any pain, but he scares me nearly every other day doing typical 5 year old stuff....jerking on his arm at the playground, whacking pillows (karate style) etc.
