Okay okay random question. What is Nedaly's relationship with Steffon and Catnis' with Sansa??
Another long response, sorrrrryyyyyy!!!
Nedaly have a bit of an advantage when it comes to the in-law relationship because Steffon is fostered at Winterfell. Steffon has always admired Ned (he’s similar to his own father, and they clearly respect each other) and he’s obviously heard many positive things about Aly from Catelyn, and the ways in which she’s similar to his mother make him even more respectful and attentive than he would be towards just any high lady. So off to a very good start.
Ned finds Steffon to be a very easy lad to teach and communicate with. He enjoys his company and the balance he provides between Robb and Jon. (Except when all three determine an injustice has occurred. Then no one is balanced. But Ned probably isn’t either, so.) (Looking at you, Petyr fucking Baelish.) Alyssandra also finds Steffon to be generally easy to manage, and she appreciates that he's kind towards her younger children. Ned doesn't understand that Baratheon fury, but he has no reason to think Steffon would ever direct it at Sansa or their children, and Alyssandra sometimes finds him a bit quiet, but overall, Nedaly like Steffon and think that he is a worthy husband for Sansa. And Steffon trusts both of them as people he can go to for advice when he can't go to his parents (for whatever reason).
Sansa and Catelyn get along well—Sansa is sweet and attentive and well-spoken and generally just a good highborn lady. Her 'rougher' bits Catelyn is very willing to put up with, as they aren't anything to be surprised by in a daughter of her beloved cousin (riding and falconry are the main things). Catelyn's one gripe is that Sansa is, flirtatious feels like the wrong word, because she's so young, maybe boy-crazy from the age of about 11. (When the Starks are in King's Landing for Stannis' Hand celebration, Sansa has an ever-rotating collection of young men at her side. Ned gives up remembering any of their names by day five and simply waves his hand vaguely and says 'your boy' when he has to refer to any of them.) (Obviously he still remembers Loras. But that's the only one.) But Catelyn's gripe is more with Alyssandra than Sansa, for allowing her to entrance all these young men then abandon them. Aly thinks this is very funny; she has no intention of ever intervening.
Stannis actually really likes Sansa. Their brands of autism go extremely well together. Stannis and Sansa frequently work on projects together, both within their duties as Prince and Lady and things related to their personal interests. (Sansa totally gets into the model ship shit Stannis and Steffon do. Catelyn cannot for the life of her comprehend why the three of them like sitting in complete silence, glaring at tiny pieces of wood.) And Stannis is honestly rather impressed by Sansa's mastery of socializing, and is very grateful for her willingness to assist Catelyn in keeping people away from him.
Sansa overall feels positively towards her in-laws. The only time she gets truly annoyed with them is following Minisa's birth. Minisa isn't a particularly difficult newborn, but Catnis kind of can't help themselves from giving a LOT of input. (She is their first grandchild after all!) And Sansa knows they mean well, but it's overwhelming and sometimes they push things that she KNOWS won't work for her and her baby and they just don't listen when she tries to tell them that! Luckily, her mama gracefully intervenes and kindly tells her dear cousin and her husband to shut the seven hells up or she'll be taking their shared grandchild to Winterfell or possibly Braavos. The suggestions are offered only when asked for after that.
