My kids were all close together, in age as well as weight and length. My 3 are all only 2 ounces apart. My earliest baby was premature and he was my heaviest. I think he would have been a ginormous baby if he went to term. He was 7 pounds, 2 ounces 19 1/2 inches long. My smallest baby was 6 pounds 14 ounces and 19 1/2 inches long. He was born on his due date. The baby came in the middle at 7 pounds even. But he was 22 1/2 inches long! He looked like string bean! He got really sick when he was a week old. He lost 3 pounds, almost half of his birth weight. When we were at the PICU and he started to get better, we had to keep him in the hospital until he got up to 5 pounds. He wore preemie clothes then and everything. He didn't wear newborn clothes until he was almost 3 months old. Healthy as an ox now. Short for his age, but everything else is fine.
