From sled tests done by Australia in 2022:

> A lap-belt restrained adult dummy in an aircraft seat, with an infant dummy in a carrier, was subjected to a 9G dynamic sled test. The severity of the pulse was based on the results of a static load test. The commercially available infant carriers tested were not able to restrain infants under crash situations.

The missing comparison is to a parent holding the baby in their arms, which I expect would also fail a 9G test. We're not making babies safer by requiring parents to take them out of babywearing carriers.

Exactly. There is no way most parents could keep ahold of a child during 9Gs, unless they have the grip strength to lift several tons.

I'd read the report. It had more to say on how carriers could cause worse injuries due to vertical orientation of the child.
