Is there such a thing as a car seat stroller combo where the car seat latches onto the stroller but is ALSO a "4ever" car seat and will transition all the way to a booster seat? I don't think it exists :(.  I have found the 4ever car seats AND the seat stroller combo where the seat latches into the stroller (fairly common) but I've never found the combo of the two.  I just hate the thought of using a car seat that will only last a year or so. But I really want the kind that latches into the stroller early on when the baby is younger. Has anyone done their research yet and know something I don't maybe? :)
