In fact I know I have. I'm always doing it.
This time I've told her that I don't want her to keep saying that my eldest child is clever, "no, I mean REALLY clever" and then saying "Of course, DS2 is too, but..."
I know there's no malice there & she loves DC but she's always said it about DH's DSis, that she's a genius etc & it's affected DH in a way that I don't want to happen with mine. She never did it on purpose (although she does play on the 'rivalry' now to get what she wants but they're both adults now) and she says lovely things about DH too.
I don't like labelling of children, especially when they're so young (3 & 21 mths) so I really needed to say it but I didn't want her to feel criticised about her own parenting. It's only now with hindsight that we know the effect it had so she wasn't to know.
I'm a plain speaking person & always need to air my troubles (sometimes a good thing, sometimes not, but it's who I am) but my PIL aren't like that & see any voicing of differing views as confrontation & take offence really easily. I don't often say how I feel to her/them to but this time I think it's worth it.
Any ideas on how to deal with this 'clash' of personalities? How I should word things in the future? I can't just shut up even if I try...
