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..........

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?
