I have a Snoozer car seat for Jax. When I have him in his seat belt harness, he ends up getting all twisted, maybe because he is still young (10 months) and is not use to it. Jax does much better with the extension seat belt connector. I place him on the Snoozer and buckle the seat belt then take the connector and connect it to the shoulder part of the belt and then to his harness. You can still use it without the Snoozer seat, but I like for him to be able to look out the window.
