Kylie Jenner says she couldn't decide on her son's name for a year because she was struggling with postpartum depression

• Kylie Jenner, 27, says she took a year to decide on a name for her son due to postpartum depression.
• Now she advises her expecting friends to choose baby names before giving birth, she told British Vogue.
• Some baby-naming consultants charge up to $10,000 to help parents pick out the perfect baby name.

Kylie Jenner says she took a year to decide on her son's name because she was struggling with prolonged postpartum depression .

In an interview with British Vogue , the Kylie Cosmetics founder spoke about being a young mother and how she struggled with postpartum depression for about a year after giving birth to each of her children.

Jenner has a daughter, Stormi, 6, and a son, Aire, 2, with her ex, Travis Scott .

"It hit me differently both times," Jenner, 27, told British Vogue, adding that she had "major baby blues" when she had her son, which made her emotional about things that she typically wouldn't be emotional about.

Jenner shared that she wasn't able to decide on a suitable name for her son for the longest time.

"On the phone with my mom all day hysterically crying, saying, 'I can't figure out his name,'" she said. "When I met him, he was just the most beautiful thing to me and I couldn't believe just how perfect he was. I felt like such a failure that I couldn't name him. He deserved so much more than that. It just really triggered me."

She said it eventually took a year to settle on naming her son Aire.

Now, her advice for all her expecting friends is to choose the baby's name before, "because when the hormones hit you can't make decisions," she added.

In a survey of 4,000 parents and parents-to-be, BabyCenter , an online pregnancy and parenting platform, found that the most popular time to decide on a baby's name is during the second trimester.

Meanwhile, 17% of respondents say they choose a name on the day their baby arrives, while 8% say they'll wait until a few days – or even weeks – before they make the decision.

Thanks to social media and celebrities, it's becoming increasingly common for parents to give their children unique names .

However, some countries like Germany have strict naming laws that forbid parents from naming their kids after places, titles, or brands.

For some parents, picking a special name for their kids is so important that they even enlist the help of baby-naming consultants to get the job done. And they don't come cheap: Some baby-naming consultants can charge up to $10,000 for their services .

A representative for Jenner did not immediately respond to a request for comment from Business Insider sent outside regular business hours.
