According to Fox News, Amy also posted a video of the moment she and Isla told Dale the news. He was so stunned when he saw Isla wearing a shirt that said "super amazing sister" that he got a little confused:

"How do you know it's a girl," he asked?

"She’s a sister, either way," Amy explained.

"Oh, she's (Isla) the sister," he responded.
