Can someone give more info, or maybe a source for the height thing? We have the Alpha Omega, which says it can rear-face up to 35 lbs, but it doesn't say anything about how tall the baby is. Ds is 20 months and about 30 lbs, and still rear-facing. The manual says to keep them rear-facing as long as they're comfortable, as it's safer.
I was planning to keep him rear-facing until he's two, as long as he doesn't hit 35 lbs before then, but now I'm worried about his height. At 18 mos, he was 33 in, but he still has plenty of legroom and headroom in the seat. What do you think?
