Warning - my post is going to be very long! I'm giving a ton of links to research, videos, and articles to help you find your answer. It really drives me crazy when I hear people say "well, my pediatrician said it's ok to forward face them at 1." While your pediatrician may have told you that, they may not be up to date on the current research - how long have they been a pediatrician? I'm sure there are a lot more things for them to be keeping current on (medications, etc) than car seat safety. So, do your own research and don't just rely on what your pediatrician says! My own pediatrician gave me a brochure that said it was ok to switch my baby around at 9 months as long as she was 20 pounds...it is NOT TRUE! Pediatricians and other doctors are not the be all end all source for everything! And, if your pediatrician was up to date on the research, they wouldn't tell you to switch your child, because it's recommended by the American Academy of Pediatrics, who your pediatrician practices under, to rear face as long as possible!! Here are the reasons why you DO NOT WANT TO SWITCH YOUR CHILD TO FORWARD FACING until they are at the limits of the car seat.
A childs' vertabrae do not fully fuse until 3-6 years old. Before then, he/she is at great risk for spinal injury. When rear-facing in a crash, the forces are spread out among the strong carseat shell and baby's strong back. The harness holds baby down in the seat and he/she is cradled and protected. When forward-facing, the harness holds babys' body back, and his/her head flies forward violenty, putting tremendous stress on the neck.
Here's the catch...the spinal column can stretch up to 2 inches, BUT the spinal cord can only stretch up to 1/4 of an inch before it snaps and baby is gone. This is referred to as internal decapitation. Babys' head will be slumped over like he/she is sleeping.
It's very important to keep babies rear-facing to 1 year AND 20 lbs. (both, not either/or) at the very least. It's actually much safer to rear-face to the limits of a convertible carseat, as recommended by the American Academy of Pediatrics. A forward-facing child is 4-5 times MORE likely to be killed or seriously injured in a crash than a rear-facing child of the same age...not a risk I'll be taking with my babies.
