"We saw a million little miracles yesterday — the best one being this girl right here... Honey 💛," she captioned photos of the couple in the hospital with the newborn.
"The pure goodness of God. story to come, but I’m way too occupied right now by cuteness," she added.
Fans, friends and family rushed to the comments to congratulate the first-time parents. "Sweetest day, sweetest mom and dad, sweetest little miracle! We love you so much Honey 🥰🥰🥰🥰🥰," her mom, Korie Robertson, gushed.
Robertson then posted another picture of her daughter taking a nap in a sweater with her name on it. "Good morning world !!! I thought you might could use 9 pounds and 5 ounces of straight up goodness 🍯," she captioned the adorable picture.
Robertson previously battled COVID-19 while she was pregnant, which was "one of the most challenging things." At the time, she said, "I know everyone experiences covid differently, but wow these symptoms are wild. I’ve definitely struggled through this one!"
"I was so sick from that, and so sick still in the morning sickness, so that was a challenge. Seriously, my heart goes out to every single pregnant person with COVID and everybody with COVID," Robertson told PEOPLE in December.
"They were telling me at the hospital, they were like, 'Man, people have to deliver with it.' I can't even imagine. So that was challenging in and of itself," she added.
Meanwhile, Korie is over the moon to be a grandmother. "The experience of watching your daughter give birth to her daughter...well, there are no words," she shared on Instagram.
"Honey James Huff you are a little miracle! We love you dearly and can’t get enough of every single detail of you," she added. "Your mom is absolutely, utterly amazing, and your dad is simply the best coach and encourager ever! There is nothing those two won’t do for you!"
"You have a whole bunch of us that couldn’t be more excited that you’re here, and are going to be loving you and rooting you on your entire life. We can’t wait to see what God has planned for you! Welcome to the fam, Honey 💛 I love you!!" Korie concluded.
