Every day seat. He is 15mo and about 20#. I like that it goes up to 50# and he is only 30", so I figured he could be in it for awhile and probably RF for at least another year or so. I have 3 across so I need a narrow seat for him coming out of his Graco carrier. I asked over on the car-seat boards, and almost everyone recommended the Radian. It is out of my price range right now. The Titan and the Safety 1st Avenue were the only other ones suggested. I went and bought the Avenue and did not like it--DS sat so low in it and I could not get it tight. It did have very high harness slots though.
