Actually, it almost never happens that people say, "you need to get this seat, this and no other one, outside of limited circumstances.
Someone trying to do three across with a 1 year old, 2 year old, and 3 year old in a Hyundai Elantra? Yeah, they're going to need three Radians.
Your 2 year old is 40 inches tall and weighs 46 pounds? Do not stop, do not pass go, do not collect 200 dollars, and buy a Regent.
Your nine month old weighs 36 pounds? The ONLY safe option is to buy a My Ride (and it used to be, import).
But it's still totally inaccurate, especially as a CPST, to describe a seat as the 'safest' one. That's really missing the core of the CPST class...to help each parent leave you with the child SAFER than he was before. That doesn't mean best practice. It doesn't necessarily even mean a 20 pound 18 month old is rearfacing.
If an 18 month old comes to your clinic in an outgrown evenflo bucket, and your coalition distrubutes evenflo combinations, congrats, you've done the job. THAT was your safest option.
The other risk you're taking, by telling a parent this is the 'safest' seat, what if the seat is recalled in 6 months? You've just told a parent that, in essence, they're bad parents if they don't buy X product, and it turns out X product is actually lethal?
All you've done at that point is create anger and distrustfulness.
It's our job as techs to INFORM of best practice. Sometimes it's even appropriate to say, "You need XYZ...here's a few seats that will do that job."
But...the MyRide is NOT the safest seat. It's just not.
