I am Aunt Zipper
YSD had her baby. DH went by himself to the hospital because he said they were trying to limit visitors. DDs wanted to face time DH and see the baby and say hi to YSD. When we called, SS picked up and showed us DH holding the baby and then panned around the room so everyone could say hi...and all of the parents and siblings were at the hospital.
Now the names - DH is Grandpa, BM is Grandma. YSDs MIL and FIL are Nana and Papa. SF is Zaide. OSD and SS and SSIL's siblings have nicknames. Everyone else is Aunt or Uncle. SSILs college roommate and wife are aunt and uncle. Family friends are aunts and uncles. YSDs neighbors are aunts and uncles. BMs housekeeper is aunt. DDs are aunts. And I am an aunt.
I don't know how to feel about this. It's fine for DDs because as half sisters to YSD they are actually Aunts to this baby. As for me, better than being called by just my first name I guess? I've said it before and I will say it again - grandkids are going to do more to highlight the separation between our families than bring us closer together.
