Actually I know IBU because I have a very nice SIL. I am jealous because my parents like her and because of the attention they pay to my toddler DN. My mum travels to see her every week and talks about her all the time (DN), meanwhile, inside I feel like a stroppy teen. It is spoiling my enjoyment of family get togethers as I end up going over all my negative feelings for hours afterwards.
i can't seem to find a way to discuss it without sounding mean and petty but not discussing it chews me up inside.
My kids are all older and no longer "cute"
