That's kind of what I figure about my house dreams. Rooms unexplored, rooms utilized, symbolizing my spirit and expectations.

The babies symbolizing the nurtureing of people and times gone by doesn't resonate within me. It's been a long time since I have felt responsible for anyone else- my daughter is 42 now.

Like Carol C said, the themes of my dreams seem to be repeated- so in that sense, perhaps babies and new rooms both stand for beginnings or things needing to be begun.

I love dreams and dreaming and most of mine are whimsical and/or bemusing. It's just that occasional one that makes me sit up and take notice.
