those infant bucket seats have a length limit, so make sure she hasn't passed that yet. i know the graco snugride is either 28 or 29 inches.
it's safest to leave them rear-facing as long as possible. we have a britax marathon, it rear faces for up to 33 pounds and then forward faces for up to 65 pounds. finn will stay rear-facing until he hits 33 pounds, no matter how old he is. little kids are flexible and should have no problem folding their legs so they fit rear-facing.
i think the seats that face rear and forward are called convertible seats. there are tons to choose from.
