"D" can refer to "Disney", "Dear", or "Darling" depending on your preference. My preference is "Darling".
DD = Daughter
DS = Son
DW = Wife
DH = Husband
If a DS or DD has a number following it, the number refers to their age. Therefore, if I referred to my DS5, I'd be speaking about my 5-year-old darling son.
MIL= Mother in law, as so it goes for FIL, BIL and SIL
TA = Travel Agent
Also, DD (2) can mean your second Disney/Darling/Dear Daughter or your 2 yr old daughter. And for some it means DDog! I would look at the posts to get its meaning in context. hehehehe
