I don't remember anyone plugging this on the board before, and I am therefore remedying that now.

This is hands-down the best Doctor Who fic I've ever read twice. It's Ten/Rose, and it's kidfic, and it /works/. Even if you don't like kidfic, it works.

Midway through the second season of NuWho, Rose gets pregnant, and life in the Tardis gets a whole new dimension. The canon chronology is derailed, of course, but watch for familiar faces popping up in different times and places.

Everyone is in character, even the children. Earlgreytea68 has them perfect. If you want your heartstrings tugged in a wonderful way, spend a few hours with this story:
