I wish someone would change those acronyms, although I know they're common usage on many websites. I don't wish to refer to my children or grandchild every time I refer to them as 'darling'.
They are my darlings, but it seems trite to use that term all the time and detracts from the genuine use of the endearment.
I was confused with the abbreviations when I started here. Have a look at 'Acronyms' (above, right). Dgd means (I think) Darling grand daughter - good luck!!!
