DD is 19 months and weighs just about 22lbs and is almost 31 inches tall. She still rides rear facing as she is still very tiny for her age. To those who extend rear facing, how long did you rear face your child? She is in a Graco ComfortSport car seat which I believe goes to 30 lbs (maybe??) rear facing. We turned DS around right after his first birthday (he was much bigger then her) but we have read alot of research since then and have decided this is best for our family. Did you wait till the weight of the seat? Is the height a consideration for this? Did you turn at a certain age (say 2?)? Just curious how others handled this. Thanks!
