Do your dolls interact? What are their relationships like?

Oh they definitely interact.
I have a couple with extended family; One and her older brother and younger sister. Her partner just had her younger sister join the group recently, and together they have a couple of kids they've "adopted". Others are close friends and co-workers. Another group is the captain and crew of a space pirate ship, and so on. They all exist in the same universe; from huge 70+ cm SDs, all the way down to 3-4 cm micros.

 

Most of my dolls are couples and families. When I have a new one, I always want another one to be his partner.

 

My dolls are connected, and they all play a part in my story! I have couples, friends, and siblings!

I have three dolls that are brothers. Damen is the oldest, Miles is the middle, and Tommy is the youngest! Damen's best friend is Jace. They also have a friend named Lucy who becomes Damen's girlfriend! There's kind of a complicated love triangle between Jace, Lucy, and Damen. Jace has a younger sister named Candy; she is friends with Damen's little brother, Miles. They go to school together. Flora and Lottie have their own story and a different universe that connects to the rest of my dolls!

 

Same with me. I don't have space or money for one more doll, but I have one SD female who is single, and it makes me crazy. She needs a partner.

 

My dolls interact. The interaction is usually my sassy characters wanting all the attention. But they mean well. The other characters just try to go along and have a nice conversation regardless if it’s not their cup of tea to talk about

 

All of my dolls have characters that interact with each other. Some characters are from a book I'm wanting to write, and some are characters from shows, but they all interact together and are friends. Some of the characters are siblings, some are dating, most are all friends.

 

Majority of my dolls interact with their respective group, since they're characters from stories I'm making. Some characters are siblings, while others are friends or partners.

 

My minifee, Neoma, I consider to be the mother to my pukifees, Luna and Noah. One day I'll shell her husband.

My littlefee likes visits from her Fae friends, including Lily the half-bunny girl.

Twig, my realpuki, likes to bother everyone else.

The only loner is my Feeple60 cuz she is so out of scale compared to the others. She seems so lonely. But I don't have plans for a friend.

 

Oh hooray, I love this topic so much
Yes, I would say my dolls interact and also that I "play" with them together as well. It's not really the active way that children play, mostly my little daydreams and mind games to keep me amused and give me something fun to think about.
I don't pre-plan characters very much. I enjoy collecting them as what I consider spirited objects and see how they make me feel and how I feel they want to interact with each other. Since I mostly have them all out on a shelf I feel like it's a community and they are at least peripherally aware of each other and form relationships based on similarities and proximity. I try to move them around so they get to make new friends and seeing them like this helps me imagine different relationships that change over time and some of those relationships go on to inspire me to photograph them together and so on. The imagining aspect of the hobby really is so much fun for me.

 

I have separate crews that interact with each other but not outside of their group. Despite loving crossovers as a kid, for some reason I don't apply it to my dolls at all. I think part of it may be that most of my dolls are based around stories I am actually writing or am going to write. As far as relationships go, I have a lot of different relationship styles and types for my characters. Only a small portion is represented amongst my dolls. For my current dolls I've got polyam characters in open relationships, monogamous relationships, half-siblings, older sister figures, complicated relationships where characters are really into each other but for compatibility reasons never progress to a relationship. Relationships are my favorite part about making characters, so, I constantly have to guard what characters I'm shelling and watch what dolls I'm buying.

 

All my dolls are adults, I don't have any underage characters. The younger characters are friends at university or hobbies, and the older characthers basically have all had romantical relationships with each other to the point that everybody is somebody's ex and there's some very complicated plot twists. Some are also parents or parent figures to my younger dolls. Currently all four of my young adult dolls are girls and none are into other girls, so there's been way less drama than if they had a boyfriend to try and share. Basically everyone in the story know about each other, some are couples, some are friends, some are indifferent towards each other, and some are sworn enemies. I enjoy writing couples the most, even if currently I have only 2 couples among my 12 dolls.

 

My dolls interact with each other as friends or lovers. I keep things pretty positive, fun, and loving.

Most of my BJDs in particular are adults, and they're paired off. They frequently do loving things like go on dates, kiss, etc. Sometimes they make love Sometimes they do BDSM stuff My Dollfie Dreams are married, and I think a couple of my resin ladies will get married one day, too.

I have one child BJD, and she's been babysat by my adult BJDs. It's so cute She also interacts with one off-topic doll who is her big sister, and it's ironic and funny because her big sister is actually a much smaller doll than she is. I am also part of their interactions because I'm their father I love my girls so much

 

Until now my dolls have been part of a trio of sister (SD Megu, SD FCS F-01 and DearSD Una), that's how it started branching out from my first doll. And as more dolls came in they became random other people who live with the sisters but are not related to the sisters nor eachother (YoSD Megu, DearSD Megu, DearSD SwD Megu on SDGr body, oldskin SD10 old F-05) but interact and get along well enough.
The DearSDs are friends, but not quite sure how the bigger girls fit in with anyone else.
My YoSD Megu, SwD Megu and (if VOLKS ever releases one) a future SDM Megu are planned to be a representation of the Three Friends of Winter but yeah, not totally sure that'll pan out.
It seems we like F-01/Megu and trios in this house

I have my first non-VOLKS, non-F-01 doll on the way and really have no clue how she'll fit in. Fingers crossed it all works out.

 

My dolls (Barbies at the moment) have a whole ton of relationships. Some of my dolls are friends since high school, some of them are family members, some of them are romantic partners, ect. I used to take pictures of them, but I don't do it as much anymore. My dolls normally don't physically interact unless it was posing for pictures or for stop-motion.
