Re: Car Seat Dilemma: WWYD? (with 2 dc or more)
I would not put a 2.5 year old in a booster. The mininum requirements to be out of a harness is 4 years AND 40lbs. A harness is safer than a booster even beyond the requirements so the longer you can keep her harnessed the better. I would also suggest a marathon or decathlon for your odd and give the roundabout for your younger dd. I did see decathlons marked down to $219 shipped.
