going abroad!!

I need some advice!! 
Looking to take our newborn abroad in July (he will be 3 months)
But unsure what to do with our pram! People say don't take it and buy a buggy because ours will get ruined but buggys are normally for toddlers I thought? 
Not sure whether to just take a sling for moving about in then pack the pram and carry cot in a suitcase, or to just take the frame of the pram and the car seat ? 
So stressful 😔😓
