maybe your future daughters soul is contemplating whether or not to enter this realm as your daughter? or this dream is showing that you are the type of person to talk to kids as equals and honestly(you answered her questions), but still have the authority of a parent (you told her to finish her breakfast) do you have ever have fears you wont be a good parent?
I don't have any fears or doubts about being a parent, and the little girls name was bb, is that significant at all?
