Two things or two sets of regulations have changed which is where it gets confusing. The regulations on the use of carseats have changed, they used to be diff from state to state but over the last eighteen or so months new national laws have been phased in so everyone has to follow the same laws regarding usage...also to confuse the issue the design standards by which carseat manufacturers make the carseats have changed mean carseats have to meet new regulations to be approved...this is still being phased in and new seats are coming the market all the time....it's all a bit confusing in the carseat world at the momentwith everything changing so rapidly......

and yes I am very sorry for your friend M2R it is worng that a person who is trying to keep her child safe should be punished like that....
