I’ve got a joie travel system and it’s really light weight! 😌
I would just wait until you’ve used it a bit postpartum (you’ll get stronger) then decide!
Look up how many KGs it is, usually it’s listed in the info about the pram. If you had a csection you wouldn’t be lifting anything remotely heavy for a while but if you have a vaginal birth with no complications from an epidural then you’d hopefully be alright after a week or so. Also we only really went for walks in the early weeks so wouldn’t have been lifting the pram into the car to go anywhere so you may not even need to worry.
Personally all travel systems are heavy till you get use to them, I have a bugaboo donkey which is a lot lighter than the travel system I had with my little boy
