Abdominal Injuries in kids that are ERF?

[AnnieA]

I posted a flyer from my state's health department about rearfacing until at least 2 on my FB page. One of my friends replied and said that she heard from a friend's spouse that is a CPST that if kids that ERF don't keep their legs crossed, like criss-cross applesauce (sorry, reformed preschool teacher!), then their legs can be forced in to their abdomens and can cause severe injuries. I've never seen anything referencing that as a potential problem with ERF so I'm wondering if any CPSTs have heard of anything like this.

What a load of "my aunt's pig's hairdresser's second cousin's uncle's through divorce' mail-man's paramour said such-and-such!" balderdash 

Someone is telling lies.  LOL.

Rear-facing is the safest way to travel, and I've never heard of that particular mechanism of injury, but severe crashes can cause severe injuries no matter what we do.

If you look at crash tests, the dummy is never "criss cross" to begin with, and regardless of leg position, the legs fly up in the air and all over the place in a crash.   They aren't going to stay crossed anyways.
