My neighbour has a two year old DS. My neighbour drives and so has a car seat in the back seat of her car. Regularly, however, when she drives to see her parents, she puts her DS in the front seat of the car. She puts the adult seat belt on him, but (because he is small) only the lap section is around him.
Her parents do only live around the corner (literally, it's just a one minute walk trhough an footpath, as opposed to a two minute drive) so she could walk, but that's a different issue.
She must be thinking that it's only around the corner so it's ok, but I remember seeing statistics a while ago that a huge proportion of car accidents happen within a mile of home.
AIBU, should she make the effort to strap her child into the car seat, no matter how short the journey?
