Carrie Underwood doesn't need a big fancy spectacle to celebrate Mother's Day. All she needs is some quality time with her favorite little guy — baby Isaiah Fisher. And with a son as cute as him, what else could you really want?

The "Church Bells" singer took to social media Sunday morning (May 8) to share how she'll spend the day designated to honor her and all mothers.

"Plans for today: snuggle with this handsome guy. That is all. Pretty sure it's going to be a great day!," Underwood writes along with the sweetest picture of her baby boy, who is pushing blocks that spell out "love you mama."

Isaiah is Underwood and hubby Mike Fisher's only child — at least for now. Underwood spilled to People that there may be more babies along the way soon.

“I’m not sure when because we’re both kind of busy these days,” she admits “But yeah, definitely. I’m like, ‘[Isaiah is] so good — I could do a few more of those!'”

But between Fisher's hockey season and Underwood's busy tour schedule, that might have to wait.

The 33-year-old country singer is currently on the road in support of her latest album, Storyteller. The tour of the same name kicked off this past January and will wind through out the country before it wraps up in Toronto at the end of May. Also along for the ride are openers Easton Corbin and the Swon Brothers.
