Re: Car Seat Dilemma: WWYD? (with 2 dc or more)
You probably need another carseat that goes past the 40lb harnessed limit. Then when your older one outgrows the roundabout, you can switch them so the baby is in the roundabout. My daughter is outgrowing the roundabout at 4 years old and only 35lbs. So doubt it would ever last to 5 years old. Harnesses are safest, so stick with those until your children don't meet the weight requirements.
