anyone have any links or images on hip bone developement??

Austins-mama · Jan 20, 2010

I know I read somewhere about the pelvic bones needing to be developed enough to withstand the crash force from a lap belt before kids can use a booster.

and also something about how adults have a natural cage in our hip bones that help protect our internal organs.

now of course I can't find it.

I'm trying to explain why a 2 year old is NOT safe in a booster even if she is nearly 40lbs. and all the usual she has to be able to sit properly etc arguements are falling flat because Mom insists she is mature enough to sit still for extended periods of time.

so I'm looking for with a little hard data.

any help ladies please..........

Not about the hips, but here's one that shows an increased risk of head injury in kids under five.

And then show her this:

Her two year old should be rear facing, but baring that I'd just go for a Nautilus or Frontier. Either of those would be better than a booster.

Is it possible she means combination seat?

With that study, since it does not include ff harnessed seats, do we still think they they are safer than boosters for 4 yr olds? I know 4 and 40lb is the minimum for boosters. Do we have research that shows a child that size is safer in a ff harness than a booster?

I had to dig through some old emails (and I know I must have originally got these off of here, but I couldn't find it on here) , but found these :

cervical vertebrae 1 year old vs 6 year old

thoracic vertebrae 1YO vs 6YO

lumbar vertebrae

anyone have any links or images on hip bone developement??
