From the updated WOWT report--see previous posts
I’ve said over and over, those little plastic half seats seem much more dangerous to me than actual seats with belts.
I’m not sure if that was what she was in (or rather “on”) but I refused to put my daughters in them. They are pushed and pushed big time. Laws enacted about “booster seats until 8” Even Disney is in on it. To me, a shoulder harness in a regular seat, with the brace that protects their little spleens, seem much safer.
If the seat slides, the kid is not protected by the harness strapping them in. IMO
