“Never in our wildest dreams did we think he’d be that big,” the proud father, Chance Ayres, told “Good Morning America.”

But the Ayres family is no stranger to larger-than-average babies. They have four other children, and two were also much larger than the average newborn. Daughter Marigold’s birth weight was 13 pounds, 14 ounces, and son Lucky’s was 13 pounds, 11 ounces.

Sonny is now home in Cambridge, Ontario, with his siblings — who range in age from 1.5 to 6 — and enjoying being the biggest little guy in the family.

“I’m taking it day by day but I’m just really happy to be home and have a good support system,” the mom told “GMA.”
