Come February, it'll be a whole new household for actress, author and busy mom of two Soleil Moon Frye: She'll be welcoming her third child -- a baby boy -- into her family to join big sisters Poet, 8, and Jagger, 5. "I can't believe that I'm going to have a boy! I'm still in crazy disbelief, it's crazy for me to say 'a boy,'" Punky Brewster's Moon Frye, who confirmed her son's gender on Oct. 16, told Us Weekly.

When the little guy comes arrives at the Los Angeles pad Moon Frye, 37, and her film and TV producer husband Jason Goldberg call home, many things will have to change around the house. Chief among them? How the Home Made Simple host and creator of the Moonfrye app structures playtime with her kids!

"I've been so much in the world of dress-up and make believe and princesses -- this whole girly world -- and now I'm like, 'Wow, it could be totally be different,'" she tells Us, asking readers with sons to write into Us Weekly's comments section with advice for her and Goldberg.

One thing Moon Frye -- who just released her kid-centric entertaining book, Let's Get This Party Started! -- knows for sure is that she'll lean on her daughters to help around the house. "I hope that since Poet's eight and Jagger's five that they'll be little mommies. We don't have a nanny and everyone in our family chips in," explains Moon Frye. "I never realized that as a mom I'd learn more from my kids then I could ever teach them. I thought I'd give them all this wisdom, and they're my biggest teachers. They're constantly inspiring me."
