Me and SIL have had a fantastic relationship throughout mine and DHs marriage, when she was pregnant with her DD and after the birth we was even closer, we would talk every day and see eachother whenever possible.
Then I found out I was expecting in December and have seen her all of twice since and mainly by circumstance rather than choice, probably speak to her once in a blue moon and not once she has asked me about the pregnancy or even how I am in general.
As it is she's her DMs "favourite" and her DD is the only grandchild, which I believe SIL thought would be the case for a long time due to the fact I have had fertility issues and none of the other siblings have or are likely to have any DC in the near future. SIL quite likes being the centre of attention and is now well aware that because I am also having a DD that she is going to lose centre stage, for reference mine and MIL still have a good relationship. MIL also provides SIL with financial support, childcare, housing and everything inbetween - I don't expect any of this but obviously SIL must think otherwise.
Am I being over dramatic or is my SIL being abit of a brat?
