Carrie Underwood and Mike Fisher celebrated a very special day with their little boy this week.

How Old Will Carrie Underwood's Son Be When He Makes His Public Debut? 

The country star and the NHL player got to watch their son, Isaiah, turn one month old on Friday. While the couple hasn't posted any new pics since their little guy's birth, they have taken tons of personal photos of the child over the last month.

To celebrated the one month birthday of baby Isaiah, here's a breakdown of everything we know about him so far.

Did Carrie Underwood Send Some 'American Idol' Contestants The Best Gift Ever? 

The Name

Underwood and Fisher struggled for month to find an appropriate moniker for their son, often arguing as Fisher jokingly wanted to name the boy "Fly" so that they could call him "Fly Fisher". As a result, the pair decided to wait and "meet" their child before choosing a name.

Ultimately, they settled on Isaiah Michael Fisher. Though "Michael" likely comes from the Fisher side of the family, it seems Isaiah might be a biblical reference as faith is an incredibly important part of their lives.

The Birth

Perhaps wanting a bit if privacy, Underwood waited a about a week to announce that she'd given birth. Isaiah was born on Feb. 27, though word of his arrival didn't come in until March 3.

The Photo

When Underwood announced her son's birth on Twitter, she shared what is to-date the only confirmed photograph of her baby boy. "God has blessed us with an amazing gift," she wrote.

The Family

Since then, the Something in The Water singer and Nashville Predators star have kept all further images of their child out of the public eye. The new parents have been having a blast with their son over the last month. Fisher has completely embraced parenthood, claiming on Twitter March that "having a child is the best thing in the world".

On March 9 Underwood celebrated her 32nd birthday and boasted on Twitter that she was spending it with a "tiny semi-bald chubby dude" who she adores.

While the new mom and dad are enjoying time at home with their son for now, it won't be for long. Underwood plans to tour this summer and has designed it so that she can bring little Isaiah along with her.
