At what ages did everyones premmie babies start weaning?

My daughter who's 6 now she started at 4 months. I've been told premmie babies are between 5months and right until the 6 months.

Can anyone tell me whether u should wait to wean them until they are 6 months corrected age or just when they hit the 6 months from when they were born?

Also, what would you feed them. I was told baby led weaning isnt good idea because they arent developmentally ready. If so would you start with baby rice and porridge for a while before starting other foods or just go for it with anything.
