We just bought Jane her "big girl" car seat - a convertible - as she's quickly approaching the height limit on her Graco Car seat that came with our travel system.
One of the top rated Convertible Car Seats is the Britax Marathon - consistently at the top of all the lists I found online. On Babies-R-Us it's $350 including tax and shipping (Canadian) but we got ours at Baby Proofing Plus for $250 tax included and free shipping in Canada.
Wanted to give y'all a heads-up as this is an AWESOME price for this car seat - and, like I said, it's one of the best out there.
If you're in the market, this is worth buying now.
Rear-facing weight limit: 30lbs - which is awesome as a few articles I read online said the longer they can stay rear-facing, the safer they are.
Forward-facing weight limit: 65lbs (insanely fabulous)
Height limit: 49"
UPDATE: Got a few questions on whether or not this seat was approved for use in Canada - some car seats are not tested in Canada or do not meet our requirements but are approved in the US. I heard back from BabyProofingPlus.com and, YES, this Britax car seat and all the car seats on their site are approved and properly stickered for use in Canada.
