The baby headed home Tuesday after being delivered by Caesarean section on June 23, a surprising three weeks early.
Her family isn't quite sure what to make of her weight.
Delaney's father, Paul, is 6-foot-2 and her mother, Robin, is 5-foot-7. Nurse Judy Nadolski describes them as "regular-sized."
"We're pretty normal," says Paul, 34.
This isn't the first super-sized baby for the Buzzells.
Their now-4-year-old daughter, Cameron, was born weighing 11 pounds, 8 ounces, and their second child, Alexis, now 2, weighed in at 10 pounds, 8 ounces when she was born.
The entire family joined The Early Show Wednesday from their home in the Milwaukee suburb of Mequon.
"We had two big girls before," Robin told co-anchor Harry Smith. "And so I thought the baby would probably be about the same size. I didn't know she was going to be (as big as she was) until she came out, although I was really, really big when she was inside. But I was pretty surprised at how big she actually was, once she came out.
"She's a chunk. She's pretty heavy. But, that's all we've known. I've never had a normal or average sized baby of 7 or 8 pounds. So, to me she's right how she's supposed to be. But, she is chunky. Two handfuls."
