Help me!

To anyone with kids already:

I adore this stroller that can be used from birth as it is adjustable underneath and lies flat then becomes a pushchair.

It’s £260 instead of the £750 we’ve been coming across for all the other prams we like.

Thing is i don’t know if a stroller type frame is sturdy enough? Do I need a pram/pushchair travel set? Or can I get a stroller?

Worried about the changing bag as well since you can’t really hang them off the back of strollers but it has good storage underneath the pushchair.

Please help! I adore it but want to be practical as well! (It’s the middle one on the pic).
