I stumbled across this show yesterday afternoon and watched it. It was really well done, had 2 Soldiers who had lost limbs, the visible injuries - one lost his leg, the other lost his hand - and 2 Soldiers that had the invisible injuries - PTSD and Traumatic Brain Injury.
It showed how the kids helped the dads cope and find their way back to normal family life but it also showed how the kids were traumatized when their dads were 'different' - and it was the invisible injuries that freaked them out the most since Dad looked normal but was acting way different. The kids of the Soldiers with missing limbs adapted to the change pretty easily. The son of the dad who got a 'bionic' hand even took his dad to school for show and tell so his dad could show his robotic hand to his son's classmates.
I was really glad to see Sesame Street did this show for military kids and also for all kids, so they can understand what is going on better.
