My DS will be 2 in a month. He's currently RF in a 2007 Britax Roundabout and is well under the weight limit (he's around 25 lbs., limit is 35 lbs.), but he's getting really close to the height limit (supposed to be 1" or more under the top of the seat). The seat doesn't expire for 2 more years, so DH would like to turn him. I had planned on keeping him RF to the limits of the seat, but I didn't think he'd outgrow it so quickly.
So...do we buy a new one with higher limits or just turn him?
