Brett Young and his wife, Taylor, are expecting their second child this summer. Brett found out he was going to be a dad again in the cutest way, his 15-month old daughter, Presley. "So I woke up and went and got Presley, and she had her zip-up sleep sack that they wear - that every adult wishes they made in adult sizes - she had one of those on," he explains. "And so when I unzipped her little sleep sack, she was wearing a shirt that said I'm gonna be a big sister."
