ok so I am trying to follow along but there are so many words used that I do not know (yes I'm new to this). 
So I figured MIL is mother in law based on the venting that has been going on. What r the others? DS? DH? Etc. throw at me all the baby lingo.                 
                             
        
Re: Baby lingo
DS = dear son
DD = dear daughter
DH = dear husband/damn husband lol
SO = significant other
MIL/FIL = in-laws
LO = little one
Thanks so much.
