LOUISVILLE, Ky. (WHAS11) -- Wednesday marks a special birthday for a child named Bryce. He was born during Thunder Over Louisville three years ago.
"I would never have expected him to come on that day but it's more meaningful that he did come on Thunder because he will always be our Thunder baby now," Nina Kjelsen, who delivered Bryce on Thunder said.
"He actually came through during Thunder. When the fireworks were going off my fiance could remember Michael Jackson's thriller going off," Kjelsen said.
She isn't alone. Those at the University of Louisville say they saw a 40 percent increase in women going into labor on Thunder last year.
"We have noticed over the past several years that once it gets towards fireworks time we see an increase in visits to our triage area with patients coming in with complaints of labor," Lisa Wright, Women and Infant Center UofL said.
"I don't think it's so much the fireworks or the aircraft, it's more of the patients activity that day especially on the days we have the nice weather patients are walking around all day in hot weather. They don't think to maybe drink enough water or take breaks," Wright said.
Perhaps the most famous baby born during Thunder is Thundasia. She was born on Thunder in 2000. Her mom had no time to get to the hospital. Thundasia was born on the sidewalk as her mom left the waterfront event.
