Aside from FF too young, he looked to have tight enough straps and proper chest clip. The RF baby, not so much...
I think this product falls into the category of "might help, won't hurt," so it's certainly not something I'd discourage someone from buying. I think it would be great for secondary cars -- where strapping the babe into the seat is *already* not routine, so the extra step of grabbing a clip won't be a deterrent. For those of us who are used to having kiddos in our cars, yeah, it's an extra step in the process... but we're not the target audience, honestly.
I did a check last week for a Dad whom I
because he was one of those parents that GOT it. He was the quintessential hyperthermia Dad -- two working parents, but Mom was the one who dropped baby off with Grandma for daycare, 99% of the time. As I explained the chaos involved in changing routine and how we go on autopilot by leaving the house and automatically driving to work, you could see him comprehend HOW these hyperthermia deaths happened. He's absolutely the target audience, because that 1 time every month or two he has Baby in the car with him, he can clip this on and it's an additional tool. We discussed things like putting the diaper bag on the front seat, etc, but why not add another layer of "memory trigger"?
We had a family in my parents' neighborhood lose a baby to hyperthermia in that exact situation, so I definitely "get" how it can happen. Given that this is one of the focus campaigns this summer, the product is timely. Practical, I don't know, necessary, probably not, but no one has figured out the solution to the problem yet, so might as well give it a go!
