Carrie Underwood thinks she has the "sweetest and smiliest baby ever".
The 32-year-old country singer is devoted to eight-month-old Isaiah - her first child with husband Mike Fisher - and doesn't even mind getting up in the middle of the night with the little boy because he is always so happy.
She said: "He's the sweetest and smiliest baby, I think, ever.
"So, that's a blessing when you're waking up at three o'clock in the morning. [When] he's smiling at you, that makes it not so bad."
Carrie thinks she and her hockey player spouse make a great parenting team as they are always mindful of each other's commitments and share the care of their son accordingly.
She explained to talk show host Ellen DeGeneres: "[Mike] is great. I think we're both really good at picking up the slack when the other one is super busy?
"So, when he has a game the next day ...I'll make sure and be like, 'OK, he needs to sleep tonight for his game tomorrow.' So, I'm the one getting up."
But the couple may not have to share night duty for much longer.
She added: "He kind of whines. It's not ever a full-on cry. It's getting a lot better. A few nights a week he'll give us all night long."
