Never thought I'd have to start this thread but it's really getting to me now. SIL has always had a problem with me from the start, I was never bothered until I had DD(2). SIL was very vocal about not being happy for us as she wanted to be the first to give MIL a granddaughter, she still came to my baby shower, came to see us when DD was born, brought gifts, etc...until DD's 2nd birthday. SIL never got DD a birthday card or present and stopped her son(DD's cousin) from coming to her birthday party. When called out by DH about not even getting DD a card for her birthday, both BIL and SIL made every excuse under the sun and apparently her card is still at theirs, they just haven't seen us but they will drop it round MIL's to pass to us. This was the beginning of last year. Still noting  when we saw them last summer when restrictions slightly lifted, SIL point blank ignored DD whenever she came up to her to try and talk to her, called her name to get her attention, asked to play, asked for a hug, etc...I still can't get over it. She's 2, she hasn't done anything to anyone, she's such a sweet little girl. Every time I look at DD, my heart breaks thinking about that time and her little face when she was ignored and rejected. Does anyone have any suggestions on how to deal with this?
