Ahhh yes, the big boys... I would strongly recommend a Britax as well. My guy got too tall for his infant seat at about 4 months. I got another Graco that wasn't too expensive. The only thing is, it fell apart fairly quickly. I got a forward facing Britax a year or so later. Had I just gotten a Britax convertable when he was younger, I would have saved the money. They are so much better put together and have much better padding. They're perfect for the taller/heavier child. I like them because their weight limits are also a lot higher. Most Gracos, etc stop at about 35/40 pounds. My guy was about that weight at 2 and was in no way ready for a booster seat which would have been the next step if you just went by size. His Britax will be good until about 80 pounds. I think the convertibles hold them until about 50 or 60 pounds. The longer you can keep them in a 5 point harness, the safer they will be. I know they're more expensive, but worth it imo.
