I think the op was just pointing out that the Symphony will RF until 35lbs, not saying that her 1yo is that weight.
You definitely want to keep your dd rear facing as long as possible. The Graco Nautilus is a great seat (I own 2 of them), just not for your little one right now!
Did you have a budget in mind? You can find a Britax Marathon (RF to 35lbs and then FF until 65lbs) for as low as $179 at allbeebaby.com, or a Graco MyRide (RF to 40lbs and FF to 65lbs) for $159 at BRU minus coupons. Those are both good seats that will last a long time. My 40-odd pound 4.5 year old rear faced in the Britax Marathon until he was 2.5 (and still could have until he was 3) and he still fits FF, but we've passed his Marathons down to his sister now. The Symphony is nice, but since it only has a 40lb FF weight limit for the harness, it isn't really worth the price.
