My husband and I bought a Chicco Keyfit 30 for our little one. I'd seen the 22 for a better price, but at the time figured we may as well go for the 30.

Now I'm second guessing myself. I've read so many accounts where children are out of the seat well before they would meet the weight/height restrictions and I'm wondering if I should exchange it for the 22 and save myself a little money.
