understanding the terminology

[PollyPage21]

Sorry if this is in the wrong place.
Please can someone explain to me the meaning of:
DS, DD and the like, I have deduced that OH mean other half but other than that I'm lost.

Thank you

Dear. (dear husband, dog etc)
Standard forum abbreviations. I think there's a list somewhere.

Dear son (or sister)
dear daughter

sometimes it’s LO - little one

Mumsnet acronym list this should help

Thank you for your replies I've got a much better idea and appreciation now on what people are writing.

Thanks for posting the acronym list, IbizaToTheNorfolkBroads
