We bought this car seat for our first child, then our second child came and we used it for him as well. one!I bought this to replace my expired Baby Trend Flex-Loc infant carseat. Buckle is not engineered with a growing wiggly baby in mind as it takes some serious maneuvering to clip in even if the baby is sitting still. Having used a Flex-Loc infant carseat already, I am happy with the updated version and have no complaints. Last night I totalled my car and my baby was perfectly safe in this carseat. My sons head had fallen forward, this is how UPRIGHT the seat is. Babies did get warm in it, but Im not sure that had anything to do with the seat itself.
