My ds1 is 6.5 years old, 50 inches tall and 61 lbs. Do you think he is ready for a booster seat? We actually have some really good harnessed seats that will still fit him, but we are trying to fit three seats in the back of our car. Now that ds3 is having to switch out of the bucket seat I don't know that we can fit all three of the nicer seats in the car anymore.
The choices are: buy another Radian (we already have two and it's the only way to fit three across) or let him sit in a booster. I'm not sure if we can afford another Radian at this time or if it would be worth it since ds1 is getting so big. Should I just move him to a booster at this time?
