DD and her cousin are really really close. They live 5 minutes down the road from us and we see them a lot. They have three children and I love the kids to bits, have always made a fuss of them, done stuff with them etc. For years they nagged at us to have a baby and finally (not because of them!) we did. Good stuff.
But my SIL is really snippy to DD, always blames her for everything, is sometimes quite nasty to her, telling her off and she has grabbed her by the arm when she was about a year old and yanked her to the other side of the room. Often she won't let DD and this particular cousin sit together at meals out etc because they play up (they don't).
Anyway, today is cousin's birthday. They are having a party at a farm nearby. Not only is DD not invited but SIL hasn't even mentioned the party. I only know because my brother mentioned it to my mother. DD wants to see her cousin, give her present and sing happy birthday and is really disappointed that she can't (I haven't told her about the party, no point and no reason to).
I am really pissed off and actually a bit upset by SIL's treatment of DD. My brother invited us over for birthday cake this evening but DH (who got the verbal invitation) said SIL was muttering under her breath about getting back from the party and getting the kids to bed etc so he didn't feel like we were particularly welcome so I've refused and said I'll leave her present in the coal hole (don't ask!) and see her next week.
Am I expecting too much? DD is a lovely little girl and I hate seeing her ignored by SIL like this when I think the world of her children and treat them as I would DD. I know we had a big debate about siblings coming to parties etc but in this case DD is really close friends with the cousin in question and I would have paid for her and stayed and helped at the party if necessary.
SIL asked me to help at the elder cousin's party a few weeks ago so she's happy to have me there when it suits her.
