Hi, Thanks for this information. Yes, my 3 year old is still is his Britax, but we're ready to move him to a seat that will accommodate a higher height/weight limit. He's currently 32 lbs and 39 inches tall. I like the Clek Foonf but worry that he'll exceed the 43 inch RF height limit well before he reaches the 50 lb limit. Is there a better seat (ie, longer-lasting RFing?) for a tall-ish kid?
I'd also like a seat skinny enough to be side-by-side with a Britax chaperone that we plan to place in the middle of our Honda CRV 2012.
Thank you - I have learned so much on this site.
Most kids outgrow most seats by height before weight. That's not 100%, but true for a majority.
Your son may be 7 years old before hitting 50lbs.
These are the sources I refer to regarding the medical need for rear-facing:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3400202/
"In autopsy specimens the elastic infantile vertebral bodies and ligaments allows for column elongation of up to two inches, but the spinal cord ruptures if stretched more than 1/4 inch"
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3256844/
" it has been reported that, by three to four years of age, the posterior and bilateral neurocentral synchondroses are fused in the atlas, (Ogden et al., 1987). These closures occurred for the other two vertebrae [in the mid and lower back] between four to seven years of age"
If your son makes it to age 4 rear-facing, that's awesome! If you want to and can rear face longer than that, I support you. But past age 4, the statistical difference in injuries between forward facing in a harness and rear facing is negligible.
It would be like winning the lottery of $15 million dollars vs winning a lottery of $15,000,100.
Clek Foonf, Diono Radian, Graco Size4Me, Chicco NextFit should get your son to age 4 RFing. Anything beyond that is total bonus so I hope you don't feel overwhelmed by the decision.
