Well, I have nothing new for the challenge (yet?), but here is a list of my stories featuring babies. All are rated G.
Dear DiaryPrimula kept a diary during the time of her pregnancy and the first months with her newborn child. - Not only journal entries but also short experiences mostly written from her POV.
A Merry BeginningThe beginning of some healing for a wounded heart and a lasting friendship. Short and fluffy.

This story, like 'Dear Diary' focuses on the pregnancy part, but there is a baby in the end... obvioulsy :)
