The main reason for the DD, DS and in my case, GD (granddaughter) use is to avoid using the child's name. A few posters use nicknames for their kids instead of the above. I really like it when the age is put with the abbreviation because sometimes it's hard to remember how old each poster's child. It makes it easier to understand the stories/problems when you know the age of the child - IMHO.
