First, you are ignoring the reason that those expiration dates exist.
First, I'm not ignoring anything. I'm telling you that there are hard and fast expiration dates set by the manufacturer, not by me. If you choose to ignore them, that's entirely on you.
Ummm, our seats are the same Graco Nautiluses that you recommended in the prior post. If you were not aware of the features of this seat, why did you recommend it?Her current seat will serve her until she is thirty pounds, at which time she can go forward facing per AAP recommendations.
Yes, the Graco Nautilus is a wonderful seat for an older child. I would not under any circumstances (and did not) recommend it for a young child as the first seat to be used after the infant carrier. I did not make any error with regard to the features of the seat.
You can, of course, choose to use the Nautilus if your child meets the minimum legal standard for both your state and the seat. However,
that would not be the best practice nor the recommendation of the AAP.
If you have a 30lb infant carrier, your child will very likely NOT make it to 30lbs in it. She will most likely outgrow it by HEIGHT first.

From the AAPs 2010 car seat info:
"When children reach the highest weight or length allowed by the manufacturer of their infant-only seat, they should continue to ride rear-facing in a
convertible seat.
It is best for children to ride rear-facing as long as possible to the highest weight and height allowed by the manufacturer of their
convertible seat. "
The Graco Nautilus is not a convertible seat, it is a forward facing combination seat. In your situation, I'd recommend a convertible seat with at least a 35lbs weight limit rear-facing and that you keep your dd rear-facing, as the AAP recommends, until she has outgrown that seat be height or weight whichever comes first. The vast majority of children in a good convertible seat can easily reach between ages 2 and 3 rear-facing.
Some recommended convertible seats, for various reasons, are:
Graco MyRide
First Years True Fit
Evenflo Triumph Advance
Britax Marathon or Boulevard
Sunshine Kids Radian
There are lots of other convertible seats out there as well that are also recommended for various purposes (travel, grandparents or part-time seats, etc).
