infant car seats britax

I want to buy a Britax Marathon Car Seat and was wondering something?

My son is six and half months old and has grown out of his infant carrier. How long to you think that it will last.

I got the Marathon for my son when he was 11 months old. He is now 3 years and 4 months, weighs 38 pounds and still uses it. I think it it lasts until they are 50 pounds, not 100% sure. Was trying to find one of the 2 booklets that comes with it, before I answered, so I could give you correct facts. Anyway, almost 2 1/2 years later, he is still using it and probably will for about another year.
Great choice in a car seat btw, easy to manage, easy to remover cover to clean, sturdy and lasts forever.

Babies on Airlines: Safety Seats Are Safer Than a Lap
SHOULD babies be buckled into a safety seat on airplanes instead of sitting in their parents’ laps? It’s a question that has been bandied about for years.
