Broken bones

We were having a lovely day, the girls had their swimming lesson and John and I were pottering around the house.  The girls were playing in the garden and asked our 4 year old neighbour in to join them.  They were having so much fun until he suddenly screamed out. They were doing gymnastics on the climbing frame bars and he had fallen off and his arm was completely bent.  I carried him home, which is literally next door and his mum rushed him to A&E.  It's broken in two places.  He must have landed on his wrist and it snapped.  I feel sick just thinking about it, the poor little boy.
