I'm new to the forums and want to make sure I'm understanding things. What do the abbreviations stand for (example: DS4, DD7, DC, HSM)? I'm guessing the son/daughter age is included but not sure on the others.

Welcome.

There's a whole list here:

Great! I hadn't run across that post yet. Thank you!

Hi Tonya - welcome!
DC is the gender nutral 'dear child' or 'dear children'
HSM may be 'homeschooling mom'
Let us know if we are being overly brief, ok?

For the record, I still don't know all of them.
