How much longer do you think DD1 has in her BLVD?

[Tammy]

I finally measured DD1's torso length- it's 15". I checked at carseat.org and they said the highest harness height on the BLVD (65) is 16.5". Her seat expires 2013 so wondering how much longer would you estimate she could use the seat? Thanks!

The rule of thumb I've read is that preschoolers & older generally gain about 1" of torso a year. So likely she'll outgrow it around the time it expires.
