It's because they are underweight. Premature babies are smaller than full term babies and are more fraigile. That is why preemies have to stay in the hospital depending on their size and weight because they need to gain more weight until they are at least five lbs so they are less fraile. A very skinny baby with ribs showing is not a healthy weight for a newborn baby so weight gain is nessisary for undeweight or preemie babies.
Weight and size of premature babies varies in regards to how many weeks of gestation, reason why they are premature, genetics, etc. There are so many variables so there is no standard size for premature babies.
