Briana's young son likes to latch himself into his forward facing car seat. while he was struggling with the latch, she noticed that his shoulders were above the car seat's top harness slots and that his head was above the top of the car seat. what should she do?

move him to a booster seat

Explanation:

          A booster seat is one where the child is allowed to sit while travelling in a car. It is a cushion seat which is used to elevate the child in the cars so that the seat belt properly fits the child. A booster seat does not have its own harness but uses the vehicle's seat belt to restrain.

          In the context, Briana's son wishes to seat in the car seat but he struggles with the seat belt as it does not properly fits him. So for his safety, Briana should shift her child to a booster seat.
