Nomad XL Plus (8063671110)

We just got and used the Maxi Cosi XL Nomad for our 15mth year old. Apparently it can be used until 12yrs. Was portable & easy to install. Only issue was the beeping sensor sometimes goes off even when seat is correctly installed or when folded for travel. Feels safe & robust though.

When ours was this age, we just used an older version of this: https://www.kiddies-kingdom.com/toddler-car-seats-15m-7yrs/63400-maxi-cosi-nomad-xl-plus-i-size-car-seat-authentic-black.html We hung it off the back of the buggy during our park days with a carabiner . Even with a small buggy without a child in, it didn’t tip. EDIT: carabiner

There are a few brands of foldable car seats, Maxi Cosi has one that's good from 15mo. They are expensive but honestly the price of getting the crappy one from the car rental place is about the same. Once you get too booster seat age, then the MiFold and the Boostapaks are good options

Maxi Cosi Nomad is very practical to carry around. We used it until our daughter grew out of the weight limit. I'd recommend it.

We always brought our own. We had a few friends that rented them abroad and told horrific tales about how dirty and unsafe the seats provided were. Often just not appropriate for age/weight of the child, buckles could be opened by the child mid drive, etc. And this was in "safe" countries like Denmark 😳 given the extortionate prices rental companies charge for car seats, we just opted to bring our own, especially as it's included on planes for under 2s. Ours was always put in the bulky luggage and never once damaged even though we never used a bag for it. We've done over 15 flights with it so far. Once they outgrow their baby car seat there are some good travel car seat options out there (e.g. maxi cosi nomad).
