One-week-old Ava Isabella Stinson — all 2 pounds of her — has made quite a dramatic entrance into the world. First her birth. Last Thursday, her parents, Natalie Paquette and Richard Stinson, rushed to a Hamilton, Ont., hospital, where she was born 20 minutes later — more than three months before her due date. She weighed 2 pounds 4 ounces at birth. Then came another complication that doctors couldn’t treat — there was no room at the inn for Ava in the Hamilton area. Lack of any empty beds in a neonatal unit in Hamilton’s McMaster Children’s Hospital forced authorities to prepare to take Ava across the border to Women & Children’s Hospital in Buffalo.
