My 7 year old ds has broken his wrist and is in plaster from fingers to shoulder. I've got lots oq questions, but the main ones are how long is he likely to be in plaster? How on earth does an incredibly physically active 7 year old get enough exercise and keep entertained with an immobilized arm? And how on EARTH do I convince my traumatized dp that it wasn't his fault, and just because it was "his watch" it happened in he's not responsible for ds's manic bike riding?
