Hi, I am not sure if its the angle of the video but its supposed to be the lap belt over the cot and the shoulder belt through the head of the car seat
In the United states you are required to put your baby in a car seat when you are driving. You would be in big legal trouble if you were caught driving with the baby NOT in a car seat. The department of Children’s services would get involved and they could actually take the baby away from you if you were caught doing it more than once. It is the safest way for a baby to ride in a car.
