The 19-month-old clearly had a good time at the Langhorne, Pennsylvania, theme park, meeting Elmo and his buddies, including Big Bird and Cookie Monster.

"Since we were in the area...we got the chance to make Isaiah's day!" the "Church Bells" singer captioned a photo of her little guy in front of the Sesame Street cast members. "Thanks, #sesameplace for the fun! We all had a blast!"

Even though all of the Sesame Street characters are pretty awesome, Isaiah holds a special place in his heart for Elmo, which may have grown even bigger after the red critter embraced the toddler in a huge hug.

The fun didn't end at the park either! After the visit, Underwood, 33, shared the cutest snap of her baby boy lying under Cookie Monster, Elmo, and Big Bird stuffed animals.

"I call this photo: Sesame OD #sesameplace," she joked.

Underwood may be busy on the road but she's still a hands-on mom known to show off funny moments in her son's life.

In August, she shared the cutest Instagram photo of Isaiah tooling around with no pants on yet rocking a snazzy fedora on his head.

"Some mornings, pants are optional...even when the fedora is not. Just kidding, we had a blowout. #KeepingItReal #momlife," she captioned the pic of her son wearing, what else, a Sesame Street diaper.

Earlier this year, Underwood told ET that Isaiah has been adjusting well to life on the road.

"He's rolling with it. It's a learning experience for all of us," she shared at the Academy of Country Music Awards in April. "We're making up the rules and figuring things out as we go along, [but] it's good."
