A bit of background info:
My sister recently moved in with a guy who has 3 sons. My sister also has 3 kids of her own, 2 girls and a boy. They live across the country from us and I have never met any her SO or his kids. This is just due to finances, I haven't seen my sister for over a year either, but we talk on the phone all the time and her kids love to talk to my DD as well. Her SO's sons are 7,5 and 3 and live with their mother during the week, coming to see their Dad on weekends and whenever else their mother needs a break. They seem to always be there for one reason or another. There is talk about going to court for true joint custody and 50-50 living situation, but due to finances right now they are trying to work with their Mother as much as they can.
So my question is: What is my role with these boys? Since I never see them I dont mean in person, I actually think this would be easier to figure out in that case, but how about in terms of gifts etc? I always send my nieces and nephews Christmas presents, and I include their birthday presents for the year in that package as well (yea, Im that kind of deadbeat aunt). So do I buy these boys birthday/Christmas presents as well, just Christmas presents, just stocking suffers, or nothing? At this point we dont know where they will be for actual Christmas morning, but I am starting my shopping so I would like to have an idea of what I should be looking for.
Sorry about the story. I am just looking for some advice and it seems that there are many eclectic families on here who might be able to help me out. THanks.
