The weight of the head in babies is quite large, and the neck is still very weak; therefore, such a nod can be extremely dangerous for the baby.
When you put the car seat against the direction of motion (that is, the kid looks back) you have to disable the airbag if your vehicle is equipped with them. The baby is placed against the back cushions, so when you crash they cause in the head and the back of the child impact comparable to a blow with a sledgehammer. Therefore, the pillow does not provide security for the kid who sits in the car seat backwards, and can even ubiti it.
