I'm considering buying a Britax Hi-Way 2, but my boyfriend thinks I'm crazy to spend $500 (with shipping) on a carseat. I kind of feel like there's no amount of money I wouldn't spend on my child's safety. What sparked this whole thing was my mom asking me to get a car seat for my DS to use in her car. My first thought was to get something safe, but inexpensive (like a Cosco Scenera or something) but I have no idea when he's going to be 35 lbs, and I have a feeling I won't be ready for him to be forward facing. So now I'm thinking I'm either going to buy a second Radian, or put my Radian in her car and get a Swedish Britax. I just have a couple questions that I was hoping someone with a Britax Hi-Way or a similar seat could answer...
-How long do you think he'll actually fit in the seat? 55 lbs is pretty straightforward, but I'm having trouble getting an idea of what height he'll be able to ride in it until.
-How long is the seat good for? I know car seats have expiration dates, but I have no idea how long they are safe to use. If I'll be able to use it for a future child, that definitely makes it that much more worth the money.
