We are into experiences, not stuff for our kids. So, this year DS will likely get a years membership in a couple of museums he enjoys where he lives.
DD and SIL will get some restaurant gift certificates because they like to eat out when they both aren’t working (which is about once every six weeks given their complicated work schedules).
No one needs more stuff.
We will include some consumables like coffee for DS, and SIL, and tea for DD.
