For YEARS I have been on my brother’s case because he refuses to correctly buckle his child in her 5 point harness, RF and now FF. He’s an engineer and I’ve explained to him about the laws of inertia and how his kid isn’t immune to them in a crash and he knows that but refuses to be a parent and protect her. He continues to ignore it. He’ll buckle the bottom but never the top and leaves the straps loose enough they don’t even hardly touch her shoulders. His only excuse has ever been is bc she doesn’t like them tight. Soooo...my question is though, she’s finally old enough for a booster, and while I’m a full believer in 5 points til they’re outgrown, in this case I can’t help but think if I get her a HBB the room for error decreases and her safety will be better. She’s 4, 38” and 44 lbs. What HBB do you think is most fool proof at getting across her and used correctly by him would you think?
