I just read the sticker on the side of Livy's car seat that it's only recommended for rear-facing until 20 pounds. She hit that at 9 months, but I didn't turn her around until right now.
The AAP recommends keeping kids rear facing until they're two or until they reach the height/weight limit of their seat.
I planned to keep her rear facing until she was two. However, I had forgotten about the weight limit thing. She's been so entertained by watching the kids in the way back seat. I hope she likes looking forward.
She feels more like a big girl now.
