Scarlett Johansson welcomed her first child, a baby daughter called Rose Dorothy, with then-fiancé Romain Dauriac this past September, and although she is still getting used to motherhood, the 30-year-old actress is completely infatuated with her firstborn.

Johansson, who secretly tied the knot with Dauriac in Montana at the start of October, recently confessed that being a first-time mother is exhausting, but in the "most wonderful way," in the latest issue of Germany's Gala magazine.

"It's exhausting in the most wonderful way. I never thought how much sleeping through the night would mean to me," she explained. "I still lack experience. Right now I'm just trying to manage. You have to first, how should I put it, learn the ropes."

But one thing Johansson can't get enough of is her baby daughter's scent. "She smells sweet, totally. I can't quite describe it, but it really makes you euphoric," she told the mag.

The 'Under The Skin' actress, who first began dating the French journalist in November 2012, also opened up about her strategy to having a healthy relationship. "I've come to the conclusion for myself that a relationship only functions if you communicate well with your partner," she said of Dauriac. "Listen to yourself and what you want, and listen to your partner."

"This is one thing I've learned over the years," the stunning beauty added. "And I've gotten better at it. Love can be difficult, but it's absolutely worth the effort."

This past March, the happy couple confirmed they were expecting their first child together, and on September 4th the 'Avengers' star gave birth in New York City.
