Are you the "go-to" person in your family?

No, but my husband is for his family. His Mum phoned him recently to query something about a payment that her daughter (dh's sister) had made on her behalf when they were together the day before   How would he know? He tried to be polite when he said "I don't know anything about it...I wasn't there...why don't you ask sister?"

When my parents were alive I was definitely the go-to person to solve problems and get things done. The problem I had with that was I was typically excluded from things UNTIL there were major issues. THEN they would call me and ask me to step in and solve the problems. Most of the time there would have been easier and/or better solutions if they had just involved me from the get go.  

I wasn't for my parents despite being the eldest daughter. I moved too far away for one, and also I was kind of the black sheep of the family. My brother was dad's go-to and my sister was mom's.

I am the go-to person for my husband and children. The keeper of all knowledge, holder of emotional labor, and so forth. Like most women. Yay.

Yes, as you said, it sort of comes with being the eldest daughter

I’m the youngest child but the only daughter so yes of course, I am the go to person.

I am THE person for my mom.  I love her dearly and am glad to be there for her, but she has no one else.  I am her "person" and average at least 45 minutes a day talking to her.  Actually, I think I can safely say that I average at least an hour a day 70% listening or doing something for her every day.  I see her at least once a week and talk to her daily ( a lot more in the summer when I am off work).

I am the go-to person for my teens and DH to some extent as well.

ETA: She does talk to my SIL about once or twice a week--probably less than an hour a week.  She doesn't call my brother unless it is "important."  My brother does show up about every six weeks or so and takes care of some things around her house. 

I am an only, so yep, all the time. Even now, my Dad will lose something, in his house, while I live 2500 miles away and ask where it is. Let alone everything else.

DH's family is the opposite on most things. They tell us nothing until we find out later. Like "your Mom's surgery went well." What! The exception is tech help. Phone, computer, etc. Then they call DH.

Nope, that's my sister who regularly communicates with both our parents (they're divorced.) My other sister lives across the country and is even less of the go-to than I am. I get jealous of her removed-ness from everything sometimes...

In DH family if any news gets to DH, I will find out months later in a "wait what?"kind of way. DH claims "well I told you that" except he didn't. Less drama for me to worry about I guess.

Actually our mom (it is my sister and me) is really good about dividing up stuff like that.  So while I do some things for her, my younger sister does other things.  She is 85 and does pretty good on her own, but stuff like ordering from Amazon or online we do for her.  Other misc items which usually involves the internet we do for her.  Traveling by plane we both have bought her tickets on her behalf.  We even sit on the phone while she checks in at the airport.  Just in case.  So yeah, we are a pretty good team. 

For my parents, yes (though they don’t need much). It’s because I’m the only child that lives near them.

I’m 7th of 8 and I was for my mom for a lot of things. The older ones were either out of the area or incompetent. The last three of us did the lion’s share of the care.

Oldest of 2 and only daughter.

For my parents, yes, but they don't lean on me much at all. The most recent clear example I could think of was when they needed help getting appointments for the COVID vaccine when it first came out.

I am definitely the go to person for my ILs. My DH is the youngest of 2 boys. BIL's first wife was no one's favorite even though they were together since HS. I think they were together about 15-17 yrs, 10 of which was dating. He and his significant other have been together for maybe 7-10yrs. But she seems to keep all of us at an arms length.

BIL is not as communicative as he used to be which has frustrated all of us but especially my IL. Our kids are the only grandkids and as a SAHM I regularly talk with the ILs more than either of their sons and give them lots of access to the kids. I also have the time and probably more importantly the patience to help them with things or coordinate getting help from others.
