Preemie babies

BabyBlu🐼 • Mom of Irish twins
For moms of preemie babies, does anyone know what timeline preemie babies follow for milestones? My baby girl was born 5 weeks early and is now 6weeks old instead of being 1 week if she had gone to her due date. Can i expect her to follow the milestones of a 6 weeks old or a 1 week old? Sorry if this is a weird question but i was told from the start to expect her to sleep more than normal, eat less, and a bunch of other things because of how early she was. Im just wondering if her milestones will also be delayed due to her prematurity?
