An Ottawa woman welcomed a great big bundle of joy at the Ottawa Hospital’s Civic campus early Wednesday morning.

Oaklyn Meredith Langille was born just after 1 a.m. Wednesday morning, weighing a whopping 13 pounds, 12 ounces.

Even more incredibly, her mother Chris-Lyn gave birth naturally; no C-section. The labour lasted only about two hours from start to finish.

Baby Oaklyn is her fourth child. Her three older brothers all tipped the scales at a higher-than-average weight when they were born: they were nine pounds, 10.7 and 11.2 pounds, respectively. Still, Oaklyn’s parents Chris-Lyn and Matthew were in disbelief when they saw the scale.

The average baby weighs about seven and a half pounds. Oaklyn’s grandmother is trying to convince her parents to add another middle name: Grace, which would make her initials O.M.G.

Mom and dad say they’re considering it.
