I posted about my dilemma before. I need a car seat in Europe for 6 weeks for a newborn before I move back to the US. I have decided to buy a used car seat so we have one for the drive to the airport, flight, and first few days in the US. Then I will buy a new American car seat. How big is the safety difference between an infant 3 point and 5 point harness, given that the baby will be rearfacing in the back seat?
I can buy a 4 year old Britax Rock a Tot (see sample info. at www.britax.co.uk/Catalogue_2003/cat_2003.htm), original owner, no accidents, but it's a 3 point harness. I have to check in a baby store to see how common 5 point harnesses are for infant seats here: Belgian safety standards are not the nirvana Americans think of when they think of European safety.
If anyone is interested in some examples, I just reviewed a car seat info. brochure from the Belgian Traffic Safety Institute, which you would think would promote best practices, and it says sure, put your infant car seat rearfacing in the front seat, just not if you have an air bag. And you see people doing it! The brochure didn't even mention 3 vs. 5 point harnesses. Made me wonder when it was printed.
Anyway, any advice about how big a difference a 3 vs. 5 point harness makes when rear facing would be appreciated.
