Carrie Underwood has shared a video of her son Isaiah giggling. She shared the video via Instagram and noted that her son’s laugh is often a better sound to her ears than even the sweetest music. “Sometimes the most beautiful music isn’t music…the best way to start the day!” she captioned the post. She also revealed a photo of them both in a Nashville park and added: “Nashville…I’m about done with this gloomy weather. It makes me tired. And I miss playing on the slides at the park ??…I mean…my son misses playing on the slides at the park. ?? Hat and jacket are, of course, @caliabycarrie” Copyright(c) 2017 RTTNews.com.
