How can I properly secure my child in a car seat twist to ensure their safety during travel?

To properly secure your child in a car seat, make sure the harness straps are snug and positioned at or below their shoulders. The chest clip should be at armpit level. Check that the seat is installed tightly in the car and the seat belt or LATCH system is properly used. Regularly check the seat's fit and adjust as needed to ensure your child's safety during travel.
