"We were amazed -- she was just so beautiful," the reality star (formerly Leah Messer) tells the new Us Weekly of seeing her tiny baby's face for the first time with husband Jeremy Calvert, 24. "She reached out and grabbed hold of Jeremy's little finger. It was very emotional."

The 20-year-old stay-at-home mom and her husband of nearly a year suffered a bit of a scare leading up to little Adalynn's birth when Messer's water broke unexpectedly, five weeks before her due date.

But it was Jeremy who was the most worked up, Messer tells Us: "He was a nervous wreck."

Now that their family of five is complete, however, the young mom tells Us that her two older girls (their father is Messer's ex-husband, Corey Simms, 22) are starting to get the hang of having a younger sibling.

"They were trying to pick her up and carry her around," Messer said. "We had to put a stop to that! I think they get the concept now."
