Molly Sims says second child is 'a game-changer'

The 42-year-old actress, who has three-year-old son Brooks and 11-week-old daughter Scarlett with husband Scott Stuber, says her house has been ''very busy'' since they welcomed their second child into the world.

She said: ''Having two kids is definitely a game-changer.''

But the 'Carrie Diaries' star, who also runs her own lifestyle website, claims her little girl rarely cries.

She told PEOPLE.com: ''I don't know why, but I make calm babies. She's probably cried six times in her whole life! I don't know how.''

The blonde beauty feels much more confident and relaxed about looking after a newborn this time round.

She explained: ''I had much more trepidation with Brooks because I didn't know what I was doing. With her, it's like, 'Okay, you're pooping, you're eating, you're drinking -- we're good!' In that way, it's been really good.''

Molly also loves dressing Scarlett up in pretty outfits.

She said: ''I always thought I was a boy mom, but I have never had so much fun dressing anyone in my life! I've become the cliché I didn't think I'd become. It's like, 'What do you want to wear today? Pink or hot pink?' ''
