My car was in an accident (everyone is fine), so I need to replace the seat I bought when pregnant, which was a Cosco Scenera. My son is 6 months, and I now know he's skinny and long, especially in the torso. I liked the Scenera, especially the price, but I'm worried he'll outgrow it by height before he's ready for a booster. I wouldn't save any money overall if I have to buy yet another seat to cover that gap. Since I have a do-over from the accident, I'm wondering if I should stay with the Scenera or switch to something else. Any thoughts?
