Better luck next time! As a mom-of-two, Carrie Underwood isn’t afraid to admit that she still makes some mistakes when it comes to parenting. In fact, the 36-year-old singer took to Twitter on Sunday, March 31, to reveal she had a little mishap when she was looking after her adorable baby, Jacob.

“Thanks to the nice lady who offered to buy me a drink at lunch today after I carried my naked, poo covered, screaming baby up the stairs and back to my table,” she said. “It was a rookie mistake leaving the diaper bag at the table and only taking a diaper and 2 wipes. Never again.”

Carrie shares her two kids, Isaiah Fisher, 4, and Jacob Fisher, 2 months, with her husband, Mike Fisher. Shortly after they welcomed baby Jacob on Monday, January 21, an insider revealed to Closer Weekly that Carrie and her hubby have been feeling very “blessed.”

“Carrie and Mike couldn’t have been more excited about introducing their son Jacob Bryan to the world. He’s the cutest thing ever and the family couldn’t be happier,” the insider said. “Carrie can’t believe how blessed she is. This is a great time for Carrie and Mike and they’re going to cherish every single moment.”

Although the “Cry Pretty” singer looks amazing after having baby No. 2 just a couple of months ago, she said that getting her body back to the way it used to be has been the hardest thing ever. “I’m going to be honest, ‘bouncing back’ after having Jacob has been much more difficult than after I had Isaiah and I’ve been pretty hard on myself lately,” she shared to Instagram on Tuesday, March 19. “I go into the gym and I can’t run as fast or as far. I can’t lift as much weight or do as many reps as I could a year ago. I just want to feel like myself again … for my body to feel the way that I know it can.”

Thanks to Carrie having both patience and determination, she knows she’ll reach her body goals one day. “I’m going to keep staying [on] the path because it is a journey and as long as I’m always working towards my goals, one day I’ll reach them. I’m going to take it day by day, smile at the girl in the mirror, and work out because I love this body and all it has done and will continue to do!” she said. You go, Carrie!
