I need a new car seat. Currently have a Britax Roundabout for my 2 yo, and I have a 7 mo that needs to move into a bigger seat. My kids are tall and tend to outgrow everything fast. I was looking at the varoius Britax seats to put my 2 yo into and move my 7 mo into the roundabout. What is the dif. b/w the Boulevard, decathalon and marathon? The seats will pretty much stay in the 1 vehicle, so travel is not a big deal. Which car seat would be best? I was looking at the Britax mostly for safety and fitting big kids longer, but am open to other brands. Thanks in advance for the help!
Sorry, I know this question is almost the same as all the other posts!!
