My daughter was 9 lb 4 oz 21.5 inches when she was born...also the biggest in the nursery, with a HUGE head, I might add. It was hard getting shirts over her head. But the funniest thing was the woman next to me had given birth several weeks early, so her son was only like 5 lbs....he was HALF the size of my daughter, so even though he was older, DD looked like she was months older than him. But I did the same...I was back in my pre-preg clothes a week after giving birth. I only gained 9 lbs with DD and I lost weight with DS because I was so sick, so I ended up weighing LESS after giving birth than I weighed before I got preg. And my OB swore DS was going to be bigger than his sister and I kept saying no, he was smaller, I could just tell...and I was right. He was only 8.5 lb and the same length.
