With our rear facing carseat, we are using the tether system but it just doesn't seem perfectly safe to me. Is there something I should know about this? Is it better to use the seatbelt for a carseat? Everytime I put him in I worry that I am doing something wrong. It hooks on either side and I have it tight, but if in a collision I feel like it could make the carseat flop out of its position! Thoughts?
Is the tether system really safe enough?
Whichever gives you the better installation is what you should use. For some people that will be latch and others that will be the seatbelt. If it is installed correctly (less than 1" of side to side movement at the belt path) then it should be perfectly safe. What is the difference between using latch and the seatbelt for you?
