Nearly a month before Meghan Markle and Prince Harry's wedding, his brother William and sister-in-law Kate welcomed their third child, Prince Louis.
It raises the controversial questions: Should they bring the baby to the wedding? Should children ever attend weddings?
Inside Edition asked The Millennial Mamas, Erin Ziering and Veena Crownholm, to weigh in.
"The answer is always yes and, being a duchess, [Kate] has every opportunity to have some help," Veena said. "They're part of the family; they want to be part of the celebrations."
But Erin thinks otherwise.
"I personally would never bring my child to a wedding," she said. "I don't think children should be at weddings, and I did not have them at my wedding."
