My 7 month old, DS2, is a butterball and about to outgrow his infant carseat. Do I go ahead and upgrade him to DS1's Britax Boulevard 70 and get DS1 a Diono Radian RXT? Or do I just get another Britax Boulevard 70?
DS1 is 28 months and 30 lbs and DS2 is 7 months and 20 lbs. I'm not sure how tall either of them are...I just remember they are both in the 80% for their height.
