Too cute! Carrie Underwood gushed during the 2019 Academy of Country Music Awards about the sweet bond her two children already have with each other. The singer just gave birth to her youngest child two months ago and it looks like the brothers can’t get enough of each other.

“He’s good,” the 36-year-old assured fans about her new bundle of joy, Jacob, on the ACM red carpet. “He has been so good here in Vegas. It is harder … trying to entertain my 4-year-old and take care of the baby. He says, ‘My baby. Where is my baby?’” She added about her oldest, Isaiah Fisher, “He is really sweet.”

The “Cry Pretty” songstress welcomed her youngest into the world on January 21 and has been in full mom mode with her husband, Mike Fisher, ever since. Luckily, a source revealed to Life & Style Weekly that the brothers clicked instantly. “Carrie and Mike couldn’t have been more excited about introducing their son Jacob Bryan to the world,” the source said while adding that Isaiah was “already itching to play with Jacob.”

“Mike’s been explaining to Isaiah that he needs to wait a few months before they can roughhouse,” the insider continued. “It’s no secret that Carrie wanted a girl, but two boys is also a dream come true. Isaiah calls Jacob his little partner in crime, it’s super adorable.”

The insider also noted, “He’s the cutest thing ever and the family couldn’t be happier … He’s happy, healthy and already smiling.” What more could parents want?

We’re sure the blonde beauty has her hands full at home and she’s getting ready to kick off her tour very soon. It sounds like the boys better pack their bags! “Carrie’s Cry Pretty 360 Tour starts in May and she’s already planning on her boys traveling with her,” the source said.

We can’t wait to see what’s in store for this new family of four.
