Country singer Brett Young, 38, and his wife Taylor welcomed their first child Monday. 

Taylor gave birth to their daughter Presley Elizabeth Young in Nashville on the evening of Oct. 21. 

“We have wanted this for so long and never could we have dreamed of something so beautiful and life-changing,” the couple told PEOPLE. “She is perfect and we are forever better because she was given to us.”

Brett posted on Instagram calling his wife a superhero and said his daughter has forever changed his world. 

PRESLEY ELIZABETH YOUNG ?? 10.21.19 Taylor, my wife. You are a superhero. Your beauty and strength never cease to amaze me. You brought our beautiful girl into this world with a level of grace and quiet confidence that I never knew existed. I’m so impressed by and proud of you. Thank you for this incredible gift. I could not love you more! // My daughter, Baby P, you’re perfect. I am so head over heels in love with you I can’t even explain it. My world is forever changed because God gave you to me. I’m going to do so many things wrong, but I promise to never stop trying, or learning, or loving you as fiercely as is humanly possible. You are my angel, and I will never take for granted the beautiful gift God has given me in trusting me with you. I will always be your rock and your safe place. I am so proud to be your daddy and I am quite certainly the luckiest boy in the world. (Side note, no boys til you’re 30). ** @people article link in bio // ?? @notbychase
