First-time mom Hilary Duff is looking forward to spending Mother’s Day with her 7-week-old baby Luca.

In a recent interview with Ellen, she gushes about her little boy. “Every single day, it seems like there’s a new face that they’re making,” she said. “He started to smile about a week ago, and that’s the coolest experience. It’s all good.”

And when they say that actresses make everything seem so easy, in her case, it really was. “I went into labor at about one in the morning and I very calmly had my bags packed and woke my husband up after about three hours of walking up and down my hallway. Then I’m like, ‘Okay, it’s time to go, let’s go now.’ We got in the car and drove to the hospital and that was it.”

So any advice for the expectant moms?  “What is to come is such an amazing journey, and a lot of work,” Duff explained to the moms-to-be. “It’s just like the best thing that’s ever happened to you.”
