Christian country singer Carrie Underwood has really embraced motherhood, so much so that she is inspired to write new songs about her firstborn son Isaiah Michael Fisher on her new album.

Unreality TV UK revealed that Underwood feels that her songs have "a whole new meaning" now that she is a mother herself. She earlier wrote "Mama's Song" and dedicated it to her mother before she wed National Hockey League (NHL) player Mike Fisher back in 2010, but now she wants to dedicate something to her son.

"I just kind of feel a little sad 'cause all my songs are about having girls," she joked as she noted some of her other female-centred tracks such as "All-American Girl" and "Forever Changed."

"Like, little boy baby Fisher's got nothin'! Eeven 'Forever Changed,' which is one of my favourite songs, is definitely like a mother/daughter kind of a song, so... I'm gonna have to get on that," she said.

Underwood first introduced her son to her fans with an Instagram post of his hand. "Tiny hands and tiny feet...God has blessed us with an amazing gift! Isaiah Michael Fisher - born on February 27. Welcome to the world, sweet angel!" she wrote on her Instagram account (@carrieunderwood).

The songstress later shared a picture of Isaiah in the cutest way possible. She had her sleeping son cradle his father's hockey stick and she wrote, "The Predators are in the playoffs! Just waiting to get called up!"

Underwood and Fisher earlier bumped heads with regards to their son's name. The American Idol alum said that she really did not like the name her husband had his heart set on.

"He keeps trying to push the name 'Bo' for our little guy," she told US 99.5 during a radio interview. "I just won't have it. Bo Fisher? I don't know. I don't like it. He thinks of it like a bow and arrow."

In the end, the couple decided on Isaiah which is a Hebrew name meaning "Yahweh is Salvation."
