When visiting parenting websites what doew DH, DD, DS etc. mean?

I know I should probably know this but I just started over with a late in life ';bonus baby'; and now I'm using parenting websites. All these little abbreviations are confusing me. Can anyone tell me the ins and outs of what all those 2 letter shortcuts mean? I have only listed a few, I know there are more. If you can tell me all of them that would be GREAT!!!When visiting parenting websites what doew DH, DD, DS etc. mean?
DH - darling husband


DS - darling son


DD - darling daughter


MIL - mother in law


FIL - father in law





and don't feel bad I was there just a few months ago too!! Enjoy the sites.
