I haven't always got on with SIL, I didn't speak to her for ages as she totally ignored my ds after he was born and when I called her and asked what the problem was, it was apparently because I hadn't made an effort to go see her(! I had a newborn and 2 other dc's I could hardly get out of bed! anyway I had contacted her and went to her house with new ds, but this is another story).
We only saw her at Christmas at PIL's house adn bumped into her in tesco after that and she always said she'd come over but never did, so I didn't bother to contact her myself.
To cut a long story short she finally came to my house this week and she was saying that she wants my dd's (aged 7 and 6) to come over for the day and stay the night. I wasn't too keen on them staying the night but was happy for them to spend the day with her, then further on in the conversation she said that she had warmed to dd1 more than dd2, because dd1 has a few behavioural issues for which she is seeing CAMHS to resolve, SIL said she feels like mothering her a bit more.
I was a bit taken aback, and she went on to say that she would never show them any difference in attention or affection and she loves them both equally ect, but I am really upset TBH.
Now I don't want dd's to go because I can't help thinking that dd2 will pick up on something and realise that dd1 is favoured or something. And I don't want my girls somewhere where there may be favouritsm, even though she says she doesn't intentionally show it, I really hate the fact that she might feel it and feel so awful for my lovely sweet dd2.
I know if I try and say something to SIL about how I don't feel comfortable with them going, she will say thats not what she meant ect but she can't take back what she said.
And now I don't wantthem to spend any time with SIL if I'm not there to see how she is with dd2.
