Yes, Santa only brings gifts for the kids - however, at my mom's house (or this year my sister's house) Santa does leave stockings for everyone. That's a community effort that happens sometime between when everyone "goes to be" and when they get up the next morning.
Gifts are trickier - for any occasion as a single parent (birthday, mother's day etc). I never "expect" my family to do anything, even though I guess they should. I guess that falls on me, even though they randomly sometimes will do it. There are occasions that no one offered (and the years my mom and sister 'forgot' about it) to take my daughter to get me a gift and so I arranged for a friend of mine to take her. Only because I thought she would feel bad if everyone else had a gift for everyone and she didn't get one for me.
This year I just moved away from my family and I will have give our babysitter money and haver her take my daughter shopping one day after school.
However, when she goes to her Dad's she ALWAYS goes with a gift for him that I have paid for (and now that he is married, that includes gifts for his wife and her 2 children as well - yep. paid for by me). hmmmmm. I guess divorcing them isn't that much different than when you were married...lol.
