The car seat also has the newborn insert so when they reach I think it’s like 63cm you just take it out and it becomes their bigger seat to last them until they’ve grown out of it
I wouldnt go for a 360 seat personally, they aren't Swedish plus tested for when they have extended rear facing and too easy for other people to turn round too early. For my twins infant seats I have the avoinut pixel pro and its amazing so so supportive especially when they were premature, and even now they are both 2 different sizes at 6 months and fits them both great, it will last till way over a year old. I didn't know much about carseat safety until o was researching for my toddler what next seat and realised how much safer rear facing is long term so best getting something to last as long as you can before changing, car seat safety UK is another good one they have some carseats that last from baby to child a little more expensive but obvs you don't have to buy a new one, also depends on the car you have what will fit best, hope this helps x
We have the cloud t and it’s great tbh. Also have the ocarro pram we bought as a bundle and you get the adapters etc. cloud t lies flat as well so if I’m just nipping in somewhere I put the car seat on the pram and lie it flat. More so when she was tiny and so footer but she’s a feisty 4 month old now and can be carried quickly or manoeuvred into her pram a bit easier than when they’re floppy newborns haha. I’d 100% recommend both pram and car seat
