Hey Guys,

Im new here, though im not new to the Step Parent role.

I'm going on my fourth year as a step parent with a 9 year old step daughter and 11 year old step son.

We have the kids Every weekend. Usually Friday - Monday, and During Holiday breaks everything is spilt evenly, so we are pretty much 50/50 custody.

Can someone catch me up on some of the acromnyms im seeing here? Obviously SO/SD/SS are pretty clear.

Still unsure on DH, DD and some others ive seen frequently.
