Are you thinking what I'm thinking? How on earth did Carrie Underwood find headphones this tiny and adorable? That's what I see when I look at the precious picture she posted on social media on Saturday night (June 6).

It looks like her son Isaiah was either worn out or just completely one with the music, as he reclined on his dad Mike Fisher's lap. The 3-month-old also looks like he knows how to be prepared for anything if and when he goes on the road with Underwood because he has his pacifier hooked onto the drawstring of his little sweat pants. Just in case.

All Underwood posted was that it was her baby boy's first rehearsal, but she didn't say if she was getting ready for her two Grand Ole Opry performances on Tuesday (June 9) or her performance on the CMT Music Awards on Wednesday.

"Isaiah's first band rehearsal ... as you can see he & his daddy were totally into it! #naptime #earmuffs #sweetdreams," she wrote.

The 2015 CMT Music Awards will air live Nashville’s Bridgestone Arena on Wednesday (June 10) at 8 p.m. ET/PT. The show will air on CMT and streamed on CMT.com.
