Carrie Underwood's husband and infant son

Recording artist Carrie Underwood posted on Instagram an adorable photo of her husband and infant son snoozing while she is rehearsing.

"Isaiah's first band rehearsal...as you can see he & his daddy were totally into it! #naptime #earmuffs #sweetdreams," the Grammy Award winner captioned her photo, which shows her baby wearing earmuffs and sleeping face-up on his father's chest.

Underwood gave birth to her first child in February. She married Nashville Predators hockey player Mike Fisher in July 2010.
