DBIL has 20 month old tiwns who are finally starting to walk their stroller which is a Graco Duo Gilder is 39 Lbs, it's the only stroller they have and can't afford to buy a lighter stroller. I hope the 20 lb limit is flexible as far as multiples go since there aren't many strollers for multiples that are affordable and lighter. I don't know much about strollers but other then for multiples the 20lb weight limit seems perfectly reasonable though. If I have to pay for my luggage I don't see why someone who has a 50lb+ stroller shouldn't have to pay to check it. But since DH and I don't have a kid yet I guess my views are a little different.
