We lived in a city and had a similar scenario. The Cosco fits into car seat backpacks easily and it’s light but annoying to tote around. I usually brought a travel stroller if we were taking cabs (GB pockit) and a bungee cord and clipped the seat so it dangled off the back of the stroller.
The Cosco Serena is the answer. I also bought a vinyl carrier/backpack for the Cosco Serena on Amazon to carry it in.
We got the Cosco Serena for traveling. It doesn’t click into a stroller, *but* is still portable depending on your stroller. If you have a bigger one, it could definitely fit in the under carriage. Ours is compact (Thule spring) and it fits perfectly when it’s upside down over the sunshade. That’s how we bring it around the airport. Looks a little silly, but it works. So maybe not ideal to just have on hand at all times, but if you know you’ll likely need it, it’s light and portable enough that you could probably bring it. They also make car seat back packs. It’s super light, so would be a little bulky but not too heavy to carry that way.
Cosco scenera a couple times (it fits in the basket of the uppababy vista, although just barely). Otherwise I go out of my way to take the bus and subway because I don’t want to risk just having him sit on my lap.
Thanks for the intel- I didn’t know about that. Per my Walmart purchase history I do have the “Next DLX” version (purchased in November 2024).
Out of curiosity which infant seat did you use and which stroller did it work with? We moved up to the Cosco scenera dlx for our older kid (3) and also don’t have a car. There are no non-infant car seats that work with a stroller.
Here’s what you do. You buy the Cosco Kids Scenera Next DLX Convertible Car Seat. It’s light and you buy a seat for your babe on the plane and you use it in the rental car or taxis while you’re on your trip. It’s cheap enough you won’t feel bad getting rid of it when you get home or if you have the space, saving for you next trip.
