Carrie Underwood singing ‘Happy Birthday’ to her son on helium is hilariously adorable

Carrie Underwood has a knack for releasing chart-topping music. So it’s no surprise we could listen to her sing “Happy Birthday” all day long — even after she’s inhaled helium. To wish her now 4-year-old son, Isaiah, a happy birthday, the country singer used a yellow helium-filled balloon to alter her voice for a silly rendition of “Happy Birthday” that somehow still sounded amazing!

Her son got a kick out of his mom and couldn’t help but giggle as she sang to him in her high-pitched voice. And once the song was over, he wanted to give the trick a try, too. Isaiah’s dad, Mike Fisher, caught the sweet moment on video and shared it with his followers on Instagram:

He captioned the video simply, “Happy birthday Isaiah.” He also included a cry-laughing emoji because let’s face it — this is hilarious:

The parents really went all out for their son’s Feb. 27 birthday, even delivering just the kind of cake he asked for. Underwood shared a photo of his over-the-top Muppets-themed cake on Instagram.

“Isaiah loves the Muppets and his favorite movie right now is ‘Muppets Most Wanted.’ He wanted a ‘most dangerous frog’ cake and he most certainly got one! And it tasted as delicious as it looked,” the mom captioned the photo.

Isaiah’s birthday comes just weeks after the family welcomed their second child, Jacob Bryan. Their second son was born “in the wee hours of the morning” on Jan. 21.

The mom posted photos of their newest addition snuggling with her, his dad and big brother on Instagram. She also noted that after expanding their family to include one more, “Life is good.”

“Our hearts are full, our eyes are tired and our lives are forever changed. Life is good,” the mom wrote:

Underwood told The Tennessean prior to giving birth that she knew being a mother to two little ones would “be a different ball game, for sure.” But she also felt sure she’d be able to make it work.

“My brain, I’m such a planner,” she told The Tennessean. “I want to know how it’s all going to go. But no matter who you are, you make it happen, you make it work, you get your team behind you.”

She also felt certain that Isaiah would be a great big brother. “I think he’ll be a really good big brother,” she said. “I think he’ll be helpful.”

And considering the mom of two just managed to pull off a birthday party, sing “Happy Birthday” with a newborn baby in her lap and keep her 4-year-old laughing and happy all the while — we’d say she was right!

Congratulations to the adorable family and happy birthday, Isaiah!
