She has the chunky plastic one (more of a baby walker than a toy pram) but is now more confident on her feet so I'dlike something lighter.
Ideally want style where doll would face her and (in a perfect world) not pink. I prefer the aesthetic of wooden toys but will go for plastic if people think they will get used more. DS had wooden pram when he was younger and just used to drag it behind him as it was a bit awkward to steer.
