So before I came along FDH sister did a lot for the kids, shopping for clothes and stuff...also this sister can't have kids physically, she is with a boyfriend who is divorced with no kids and they have been together for longer than FDH and I,...
But her boyfriend does not want to get married again...and definately doesn't even want to adopt kids...

So recently FDH sister has told Fdh that she does not like the way I treat the kids, that I'm too harsh on them, that I make them cry.
FDH stood up for me and said that I've got the kids best interests in mind and I love them...AND that he thinks the rest of his family has been babying his kids and he is thankful that I've pointed out to him little things that his kids should be capable of that they can't do, because someone always does it for them...

FDH has had to say this twice to two of his sisters
The last time including, "this isn't high school stop wispering and if you have a problem tell me"

Neither sister has talked to me since.
I used to be close to the older one, and it bothers me that she just doesn't talk to me...

I don't know what I can do about it.
