[This Cosco seat](https://a.co/d/aYRpGmm) is a seat that is perfectly appropriate for an infant rear facing but ALSO can be forward facing. They’re quite lightweight, perfectly safe, and very reasonable on cost. I suggest getting one of those for the trip.
We got a Cosco one for traveling. It’s a no frills thing, but it’s light and gets the job done. This looks to be the newer version of what we have: https://coscokids.com/products/onlook-2-in-1-convertible-car-seat-cc331 Also, assuming you know this, but don’t drink the water. Stick with bottled water, especially for the kid if you’re making formula. The resort will tell you the water is fine. It might be in some places in the hotel… it also might not be all that great in for example the ice makers. My wife’s entire company learned this the hard way at a conference at all included hotel thing in Mexico.
I have the same problem. It doesnt move much side to side but, even with a rolled up towel, the car seat easily tips forward towards the back of the backseat when rear facing
I uber all the time with my toddler and we use the Cosco Onlook car seat and use a harness to sit it on our travel stroller. It has worked extremely well and its lightweight and easy to install in cars. My toddler just rides in the tethered car seat when we get out of the uber.
You should definitely check if the Nuna Rava is airline approved, there should be a small airplane logo stamped on it if it is. We have traveled literally around the world with the 2 in 1 Costco Onlook. We got it on Amazon and use it in the car regularly for caretakers and it was so easy to travel with. It worked great on the plane and then was easy to fasten into the car. Good luck!
there's a super light one by Cosco (not Costco) that's great for taking on a plane and light for carrying around the airport.
He probably won’t fit in the doona. Infant seats can not rear face, even on a plane. I would bring a cosco seat and use it on the plane. That’s what we did when we took our 18mo to Europe. She did end up being held for sleep but she was in her seat otherwise. Good luck!
We used it rear facing. Easier to keep her from kicking the seat in front. Movies did not hold her attention at that age so we didn’t attempt it. We have since used it forward facing on planes as well.
Cosco until big/mature enough for RideSafer.
If the child is over two, you’re buying a seat for them regardless, correct? The only negative I ever encountered was flying with my toddler alone meant I was responsible for getting them and the seat onto the plane myself. Both can be heavy and unruly at times. I loved having their seats on the plane though. It was just like the car for them, no trying to get down, or wanting to be held. And they could easily sleep. If you have a helper, even better. Plus you’ll have a car seat where you’re going, and it won’t get broken or lost from checking it. If you can buy a cheap lightweight seat, it’ll help a bunch. We had a cosco seat from Walmart we only used for travel. I think it weighed less than 10 lbs.
I’d bring it. I have kids here, and the subway can be hard…no working elevators or filthy ones. Lots of stairs with bad weather and tired kid. Taxis also go super fast from the airport to the city. The car services might have car seats, but there’s no guarantees about their condition, size, installation and availability. I have a cosco for when I take my kids out…it sits (awkwardly) right on my travel stroller.
We still do a Cosco car seat because it's light and transportable. When they grow out of that it will be a CARES harness.
Cosco car seat. Literally lighter than my diaper bag. While strolling through the airport put the seat in the stroller. I'm assuming you have a double?
