Like many moms, seasoned and new, Kelly Osbourne finds parenthood as daunting as it is rewarding.

The TV personality, whose famous family will soon return for season two of The Osbournes podcast after a five-year hiatus, reflected on life after welcoming her first baby, son Sidney, with partner Sid Wilson late last year.

"I'm a mom now, I love it. It's the best thing that has ever happened to me," Kelly exclusively told E! News, adding, "It's scary as f--k because you don't want to make a mistake."

Citing a stressful attempt to trim her son's fingernails, the 38-year-old continued, "It's all these little tiny things and these mistakes that you ultimately make because you can't learn unless you make a mistake. It's just unfortunate that you have to do it with a baby."

As she navigates life as a first-time mom, the daughter of Ozzy Osbourne and Sharon Osbourne has leaned on her parents for support. When asked what was the best piece of advice they have given her, she told E! News, "That it's not about you. Now, your life is about your child."

Sharon also emphasized the importance of self-care to the couple's daughter. "My mum is trying to get me to not be so attached to the baby right now, because I don't do anything unless it has something to do with my baby, and she's like, 'You have to take some time out for you,'" Kelly said. "But I try and do it, and the next thing I know, I'm sneaking out the back door to go home to be with my baby."

Meanwhile, Kelly is enjoying watching her son develop and reach major milestones. "He is almost crawling, which is amazing," she said. "He is kind of like scooting backwards and turning in circles."

And baby Sidney has also been showcasing another move that has been melting Kelly's heart. "Now my favorite thing is that he is, like, mom-obsessed, just where, if he sees me, he is reaching for me," she told E! News, "and I love it."

Season 2 of The Osbournes podcast is set to premiere Sept. 12.
