Nick Carter Is Officially a Dad of 2! See the Cutest Photos of His Son While We Wait For More of Baby Saoirse

Nick and Lauren welcomed their first child, a son they named Odin, on April 19, 2016 — and talk about seeing double, Odin looks just like his daddy! On his third birthday, Nick wrote on Instagram: "Daddy loves you more than anything in the world. Thank you for being in my life," then later shared a video of the little one singing "Happy Birthday" to himself. Looks like he's also got talent just like his dad!

The couple welcomed their second child, a rainbow baby girl they named Saoirse (pronounced SEER-sha), on Oct. 2, 2019. After sharing in September 2018 that Lauren had suffered a miscarriage, Nick wrote a sweet note to Lauren when sharing the first-ever photo of baby Saoirse's face.

"To my incredibly strong wife," he wrote. "For two years I watched you endure some of the hardest things a husband could ever witness. Going through the ups and downs of pregnancy all in the hopes that just maybe, with a little help from up above, we would get to this point. I'll never forget the moment You asked me what I wanted for my birthday, I said nothing. But deep down inside I knew what I really wanted. So on January 28th 2019 when I walked out of that bathroom with that positive test I already knew that Saoirse was coming back to us. I just want to thank you for giving me the life, love, and family that I always wanted. You are a true warrior and I love you." So dang sweet.
