So happy for you that your son doesn't need surgery! My ds was 4 when he broke his tibia and fibula. It really sucked. No decent pain management and he couldn't use crutches, had to be carried everywhere. He healed up fine though and you'd never know he had had a broken leg now. Those young bones mend very well and fast! He needed a bit of physical therapy to re learn how to walk properly. Good luck with the rest of recovery. Ds learned how to play chess very well during that time. I scourged the second hand children's shops to find puzzles and games and any little thing that would keep him happy for a few minutes. Magnets on a cookie sheet worked really well. Best to you and your family.
