@batman21 For anyone who ever has to have this conversation with a “friend” or family member, Newton's 2nd law:
Force = mass x acceleration (deceleration). A baby that weighs 11 lbs (5 kgs) will require 220lbs (100kgs) of force for grandma to hold on to her in an accident at 45mph (20 m/s).
And that’s for an infant! The average 12-month old weighs twice that, and I don’t know anyone who could hold onto 400+ lbs during a car accident. And that doesn’t even address the dangers of airbags on little unsecured heads and bodies!
For the “I turned out fine” crowd, it’s important to note that infant mortality has been cut in half since 1980:

Why would anyone want to double their kid’s chances of dying by ignoring modern safety practices?
