In one of the sweet pics, posted to her Instagram Stories, Lauren is cuddling baby Dutton as he is swaddled on her chest.
“Everyone in the room, including Lauren and me, were shocked we had a 9-pound baby! Not sure where he was hiding in her belly?!” the country singer, 36, joked to PEOPLE.
The couple announced their pregnancy news in December, sharing a video of an ultrasound of their baby on Instagram.
We prayed every day for months and obviously our prayer was answered, but I know there are a lot of unanswered prayers out there,” Lauren said.
