Some of those kids are pretty big.
A child is much more vulnerable in an accident as they are still growing. Their proportions are not the same as adults’. Their heads are 25% of their bodyweight. If adults’ heads where the same proportions the head would weigh 20kg.
The child’s skeleton has not yet been solidified into bone, but is still soft, mainly consisting of cartilage. When subjected to violent force the skeleton will bend rather than break. On an adult the rib cage protects our vital organs such as heart, lungs, spleen etc. On a child this is not the case. When flung against the harness in a forward facing child seat the rib cage cannot cope with the force on impact and the organs inside might be injured and damaged. Same thing with the neck. The spine has not solidified. It is soft and might stretch and snap, in which case the bone marrow is the only thing left preventing internal decapitation.
There are no reported incidents of rear facing children hurting their legs. There are a multitude of reported incidents of children hurting their necks (or worse!) in forward facing car seats. Proper rear facing group 1 car seats are positioned so that there is space for the legs. Have a look at the pictures in the gallery to see what they look like.
Children that are have always been rear facing will not know any different and will be happy and content in their rear facing car seats. You can use the same stimulations you would use otherwise during a journey: toys, pictures hanging in front of the child, playing music or stories etc. If there are adults or older children in the back seat with the rear facing child, they can interact much better than if the child was in a forward facing seat, as they can look at each other and play together (without being able to hit each other as a little added bonus for less parental stress on journeys).
