Carrie Underwood details son Isaiah's first Christmas

NASHVILLE, Dec. 31 (UPI) -- Carrie Underwood says son Isaiah enjoyed his first Christmas.

The 32-year-old singer revealed Wednesday on Twitter that she and husband Mike Fisher spent the holiday with the 10-month-old and other family.

"Yes [he had a good Christmas]!" she wrote in response to a fan. "He got way too many toys from family and friends, but got to see his cousins and grandparents in OK and Canada!"

Underwood and Fisher married in July 2010, and welcomed Isaiah in February. The singer gushed about the infant at the American Music Awards in November, telling Entertainment Tonight her son is "the best thing" she and Fisher "ever did."

"At the end of the day, no matter what, I'm a mom," she said. "It just makes everything, I don't want to say less important because this is such an incredible night and I'm excited to be part of it, but the mom card just trumps everything."

Underwood shared a photo of Fisher and Isaiah on Sunday, telling fans her son spent the day watching cartoons. She followed up with a funny post Tuesday, writing, "Welp, I got peed on this morning. What a way to start the day! #momlife #MomProblems #WhereAreTheDiapers."
